Abstract:

River Birira stretches through Kitagata town council and near Kitagata hot springs in southwestern Uganda. These areas receive an inflow of people that utilize the hot springs because of the belief of healing associated with the water. This has led to increased human activities along river Birira, which may negatively impact on the ecological integrity of the river. A number of countries have developed biological monitoring systems to assess the water quality of rivers and streams, however non has been developed specifically for Uganda. This study therefore aimed to assess the water quality of river Birira and determine the compatibility and usability of Biological Monitoring Working Party (BMWP) and Tanzania River Scoring System (TARISS) biological monitoring systems in a Ugandan setting. In this study, four sampling sites were selected basing on human activities taking place along river Birira. The sites were assessed for both physico-chemical and biological parameters using standard methods. In this study 9 physicochemical parameters were used in the computation of water quality index (WQI). Findings of this study indicated that sites in close proximity with the bathing pool of Kitagata hot springs were severely impacted and had undesirable water quality. Results also showed that the water of river Birira is generally unsuitable for human consumption, therefore, needs thorough treatment before consumption and domestic use. This study further revealed that both BMWP and TARISS monitoring systems give similar deductions about the water quality of river Birira. Therefore, any one of the monitoring systems can be adopted in assessing the water quality of the River.

Abstract:

An accurate assessment of cast steel components including cast imperfections minimizes production rejects and moreover facilitates lightweight design. In order to improve the fatigue assessment of cast steel structures exhibiting macroscopic imperfections, a generalized Kitagawa diagram based on the linear elastic fracture mechanical theory is presented. Therefore, single-edge-notch-bending crack propagation tests as well as extensive fatigue tests utilizing un-notched base material specimens are conducted. Both the stress intensity factor threshold range and the plain material fatigue limit act as basis to set-up the generalized Kitagawa diagram. In addition, fatigue tests under rotating bending as well as axial loading using round V-notched specimens with varying opening angles are additionally conducted for validation. It was observed that the notch-stress-intensity-factor (NSIF) calculation based on El-Haddad’s material length leads to slightly non-conservative designs for this cast material. But if the intrinsic material length is calculated by Neuber’s stress averaging approach or Peterson’s microstructural length instead, the presented NSIF-based fatigue assessment reveals a sound comparability to the experimentally determined fatigue reference strength. Summing up, the presented generalized Kitagawa diagram provides a feasible engineering-applicable fatigue assessment tool incorporating varying imperfection opening angles and load conditions for G21Mn5 cast steel.

Abstract:

Cette thèse s’inscrit dans le cadre général de l’étude de la tolérance au dommage des pièces tournantes dans les turbomachines d’hélicoptères et porte sur la résistance à la propagation de fissures courtes 2D.Pour mener à bien cette étude, l’effet de la température est d’abord étudié sur les seuils de propagation de fissures longues à R=0,1 sur deux alliages TA6V et Ti6242 de microstructure bimodale (20°C et 400°C pour le TA6V et 20°C, 200°C et 500°C pour le Ti6242). Au voisinage du seuil, le comportement effectif(après correction de la fermeture) est sensiblement identique pour les deux alliages aux températures testées. La fermeture est principalement induite par l’oxyde à haute température et par la rugosité des surfaces de rupture à température ambiante.L’évolution du seuil de propagation en fonction de la longueur de fissure a ensuite été étudiée à R=0,1. Un outil de détermination automatique du niveau de fermeture a été mis en place afin d’améliorer la mesure pour des fissures très courtes (80 μm). La fermeture mesurée pour différentes longueurs de fissure obtenues par usinage progressif du sillage plastique est comparable à celle obtenue au cours de la propagation d’une fissure courte 2D au seuil, sauf pour les hautes températures où la fermeture induite par l’oxyde se développe rapidement. Les différences de comportement entre fissure longue et fissure courte sont expliquées par une contribution réduite de la fermeture lorsque le sillage de la fissure est réduit.Un critère de non-propagation s’inspirant du formalisme initialement proposé par Kitagawa et une loi de propagation adaptée permettent de mieux prédire la résistance à la propagation des fissures physiquement courtes
Damage tolerance analyses of rotating parts, containing 2D-short crack, in turbomachines of helicopters is the main focus of this thesis.Fatigue crack propagation tests were performed at R=0.1 on two bimodal Titanium alloys at different temperatures (20°C and 400°C for TA6V and 20°C, 200°C and 500°C for Ti6242). Near-threshold effective behaviors (after crack closure correction) were approximately the same for the two alloys attested temperatures. Crack closure was principally due to oxide layer at high temperatures and to fracture surface roughness at ambient temperature.Then the variations of the crack propagation threshold with crack length was studied at R=0.1 and different temperatures. A numerical tool was developed to automatically detect crack closure level more precisely for, as short as, 80μm cracks. Crack closure levels measured at different crack lengths obtained from progressive machining of the plastic wake were quite similar to the ones obtained during propagation of 2D-short cracks near the threshold, except at high temperatures where oxide-induced crack closure developed rapidly. Differences in behavior of long cracks and short cracks were explained by a reduction of crack closure level when crack wake was not fully developed.A non-propagation criterion based on formalism initially proposed by Kitagawa and a modified-Paris propagation law allow to give a better description of physically 2D-short crack propagation resistance

Abstract:

Ces travaux de thèse concernent la caractérisation en fatigue à grand nombre de cycles de l’alliage d’aluminium moulé A357-T6 (AS7G06-T6) en présence de défauts de type retassure. Six coulées ont été produites pour étudier deux familles de défauts : les retassures de type cavité et les retassures de type spongieuse avec un grade de nocivité qui varie entre 2 et 4 (selon la norme ASTM E 2422). La limite de fatigue en traction positive (R = 0.1) a été estimée en fonction de chaque type de défaut pour N = 2∙106 cycles. Des essais ont été également menés sur des éprouvettes dégradées en surface avec un défaut artificiel. Le défaut artificiel est caractérisé par une variation très localisée de la morphologie (usinage au FIB et par EDM) représentative de la microporosité interdendritique. La morphologie locale et globale des défauts naturels est étudiée grâce à des simulations numériques aux éléments finis. Les calculs numériques sont conduits sur la géométrie réelle d’un pore reconstruite à partir d’un scan en μ-CT. Deux géométries équivalentes ont été proposées pour approximer la morphologie d’un défaut naturel : une sphère et un ellipsoïde équivalent d’inertie.L’effet de la position du défaut sur l’évolution des champs mécaniques a été également étudié en conduisant des simulations numériques aux éléments finis sur la géométrie réelle du pore. Deux approches ont été proposés pour simuler un diagramme de type Kitagawa-Takahashi: (i) la Mécanique de la Rupture en Élasticité Linéaire (LEFM) (ii) un critère de fatigue detype Defect Stress Gradient (DSG), les deux modèles ont été testés dans le cas d’un amorçage sur un défaut de surface et interne.Une campagne d’essais de fatigue (R = 0.1) a été conduite à l’échelle d’un composant industriel. Une pièce réalisée par fonderie en A357-T6 a été testée dans une configuration saine et dégradée avec des défauts artificiels de surface. Un critère de type DSG, qui prend en compte l’effet du gradient de contrainte à l’échelle macroscopique de la structure, a été proposé.Le modèle a été validé par un calcul aux éléments finis du composant en utilisant une routine de post traitement des données, qui affiche en sortie la cartographie de la taille admissible du défaut de surface en chaque point du modèle simulé
The purpose of this work is to characterize the high cycle fatigue strength of the A357-T6 (AS7G06-T6) cast aluminum alloy affected by natural casting defects (shrinkages). Six different castings have been manufactured in order to study two shrinkage types: the cavity shrinkages and the sponge shrinkages with a defect grade ranging from 2 to 4 (as defined by the ASTM E2422 standard). High cycle fatigue tests have been carried out in order to estimate the fatigue limit under positive tensile loading (R = 0.1) for each defect type at N = 2∙106 cycles. The effect of the local defect morphology has been investigated performing several fatigue tests on specimens with artificial surface defects characterized by a local morphology modification (FIB and EDM machining). The artificial defect size and morphology is representative of the natural interdendritic porosity. The local and global defect morphology of the natural defects have been studied by means of finite element simulations conducted on the real shrinkage morphology reconstructed from a μ-CT scan. Two equivalent geometries have been proposed to simplify the natural defect morphology: a sphere and an inertia - equivalent ellipsoid.The effect of the defect position on the mechanical filed evolution has also been studied by means of finite element simulations performed on the real defect geometry. The analysis of the Kitagawa-Takahashi diagram has been performedby using two different approaches for both internal and surface defects: (i) the Linear Elastic Fracture Mechanics (LEFM)(ii) the Defect Stress Gradient (DSG) fatigue criterion. An experimental campaign has been performed at a component scale. A casted A357-T6structural component has been tested with two different configurations: as received and degraded with artificial surface defects. A DSG fatigue criterion,taking into account the effect of the stress gradient at the macroscopic scale of the component, has been proposed. The model has been validated by means of finite element simulations using a data post-processing sub-routine that gives as output the critical defect size map at each point of the simulated model

Abstract:

Il été prouvée dans plusieurs études de la littérature que la taille d'un composant affecte sa tenue en fatigue et cette tendance est plus prononcée dans le régime de fatigue à grand nombre de cycles. Plus précisément, une baisse de la limite de fatigue est observée et est souvent expliquée par l’augmentation, avec l’augmentation du volume sollicité, de la probabilité de trouver un défaut critique ou une zone plus faible dans le matériau. Le présent mémoire fait partie d'un projet de recherche français (QUAUSI) regroupant plusieurs partenaires industriels et académiques qui vise à contrôler la qualité d'usinage des composants structuraux d'avions. Un des défis consiste à définir un critère approprié d'acceptabilité de défauts pour la conception en FGNC. Le critère doit être capable de prendre en compte une large gamme de défauts de surface et de composants de tailles et de géométries différentes. L'objectif principal étant de mieux comprendre l'impact des états de surface périodiques (caractéristique du type d'usinage utilisé) sur la limite de fatigue, Il a fallu d'abord vérifier si un effet de taille peut être observé quand un nombre croissant de défauts de surface simples sont introduits à la surface d'échantillons polis. Le matériau d’étude est l’alliage d'aluminium 7050 (Al Zn6CuMgZr). Une grande campagne d'essais de fatigue sous charge de flexion plane à R=-1 est effectuée sur des éprouvettes présentant des défauts hémisphériques, de différents tailles et nombres, et des états de surface usinés. Les résultats des essais ont permis de caractériser à la fois l'effet Kitagawa et l'effet d'échelle sur la tenue fatigue. Une approche probabiliste basée sur le concept du maillon le plus faible associé à un critère d'amorçage de fissure de fatigue approprié est utilisée pour prendre en compte la répartition des contraintes et la taille du volume fortement sollicité. Les prédictions utilisant des simulations EF montrent un bon accord avec les résultats expérimentaux et illustrent l'importance de prendre en compte l'effet d'échelle lors de la conception de composants contenant différents types de défauts de surface ou de motifs de rugosité.Mots-clés : Défaut de surface, fatigue à grand nombre de cycles, diagramme de Kitagawa-Takahashi, Le plus faible concept de lien, alliage AA7050
The size of a component has been proved in several studies of the literature to affect the fatigue strength and this trend is known to be more pronounced in the High Cycle Fatigue regime. More exactly a drop of the fatigue limit is observed and this evolution is very often explained by the probability to find a critical defect or a weakest zone in the material as the stressed volume rises. The present manuscript is part of a French research project gathering several industrial and academic partners that aims to control the machining quality of aircraft structural components. For one part of the project the challenge is to define a proper defect acceptability criterion for HCF design purpose. It must be able to account for a large range of surface defects and of component sizes and geometries. Even though the primary objective was to better understand the impact of periodic surface micro-geometry patterns (characteristic of the type of machining used) on the fatigue limit, we thought that it was first necessary to check if a size effect can be observed when an increasing number of artificial simplified surface defects are introduced at the surface of smooth specimens. The aeronautical material under investigation is a 7050 Aluminum alloy (Al Zn6CuMgZr). A large fatigue testing campaign under fully reversed plane bending loading is undertaken on specimens with artificial surface hemispherical defects. Defect number varies from 1 to 44 per specimen whereas their size ranges from 60 µm to 800 µm. Testing results allow the characterization of both Kitagawa effect and scale effect on the fatigue response. A probabilistic approach based on the weakest link concept together with a proper fatigue crack initiation criterion is used to account for the stress distribution and the size of the highly stressed volume. Predictions using FE simulations show a good agreement with experimental results and illustrate the importance of taking the scale effect into account while designing components containing different types of surface defects or roughness patterns.Keywords : Surface defect, HCF, Kitagawa-Takahashi diagram, Weakest link concept, AA7050 alloy

Abstract:

L’objectif de ces travaux de thèse est d’étudier l’influence du rapport entre taille de défaut et longueur caractéristique de la microstructure, sur la limite de fatigue pour une durée de vie fixée d’un matériaux métallique,dans le cadre de la fatigue à grand nombre de cycle (FGNC). Le fer pur Armco est choisi comme matériau d’étude, car sa microstructure simple présente une seule longueur caractéristique à l’échelle mésoscopique (échelle des grains) : la taille de grain. Le but de l’étude revient ainsi à étudier la compétition entre un effet de structure (défaut surfacique)et un effet matériau (taille de grain) dans le cadre de sollicitations mécaniques en FGNC.Afin d’obtenir une taille de défaut comparable mais aussi inférieure à la taille de grain du matériau, un protocole thermomécanique a été élaboré pour augmenter la taille de grain. Des essais de FGNC, utilisant des éprouvettes issues des deux tailles de microstructures (matériau initial et celui écroui traité) dans lesquelles sont introduits des défauts hémisphériques de tailles différentes, ont été effectués pour estimer les limites de fatigue pour différents rapports taille de défaut / taille de grain. Lorsque les diagrammes de Kitagawa sont présentés en valeurs relatives(limite de fatigue / celle du matériau sans défaut en fonction de la taille de défaut / taille de grain), il existe une seule courbe qui combine les deux microstructures. Ce diagramme de Kitagawa sans dimension permet ainsi d’analyser la réduction de la limite de fatigue causée par un défaut. L’utilisation de la taille relative du défaut par rapport à la dimension microstructurale caractéristique apparaît comme plus pertinente que l’emploi de la taille physique réelle du défaut.Ces résultats expérimentaux sont utilisés pour reproduire les essais en FGNC avec des simulations Éléments Finis sur des microstructures 3D représentatives du fer Armco. La compétition existant entre la concentration de contrainte induite par le défaut géométrique et les régions fortement sollicitées de la microstructure engendrées parl’anisotropie du comportement mécanique des grains est étudiée. Un critère mésoscopique (à partir des grandeurs mécaniques moyennées par grain) basé sur une approche statistique permet de retrouver l’allure du diagramme de Kitagawa adimensionné, c’est-à-dire la taille relative du défaut critique à partir de laquelle ce dernier prend le passur l’hétérogénéité de la réponse de la microstructure et conditionne ainsi la tenue en fatigue du polycristal. La modification du critère mésoscopique par la prise en compte des hétérogénéités intragranulaires (via l’écart-type par grain des grandeurs mécaniques) est discutée
The objective of this thesis is to study the influence of the ratio between the defect size and themicrostructure characteristic length on the fatigue limit (for a fixed fatigue life) of a metallic material, under highcycle fatigue (HCF). Pure Armco iron is chosen because its simple microstructure has a single characteristic lengthat the mesoscopic scale (grain scale) : the grain size. The aim of the study is thus to study the competition betweena structural effect (surface defect) and a material effect (grain size) in the context of mechanical stresses in HCF.In order to obtain a comparable different grain size, a thermomechanical protocol has been developed. HCF tests,using specimens from both microstructure sizes (initial material and processed hardened material) in which hemisphericaldefects of different sizes were introduced, were performed to estimate the fatigue limits for different defectsize / grain size ratios. When Kitagawa diagrams are presented in relative values (fatigue limit / fatigue limit ofdefect free material versus defect size / grain size), there is a single curve that combines the two microstructures.This dimensionless Kitagawa diagram thus makes it possible to analyze the reduction of the fatigue limit inducedby a defect. The use of the relative size of the defect with respect to the characteristic microstructural dimensionappears to be more relevant than the use of the physical size of the defect.These experimental results are used to reproduce the HCF tests with Finite Element simulations on 3D microstructuresrepresentative of Armco iron. The competition existing between the stress concentration induced by thegeometrical defect and the highly stressed regions of the microstructure generated by the anisotropy of the mechanicalbehavior of the grains is studied. A mesoscopic criterion (involving mechanical quantities averaged by grain)based on a statistical approach allows to find the evolution of the dimensionless Kitagawa diagram, ie the relativesize of the critical defect from which it predominates over the response heterogeneity of the microstructure and thusgoverns the fatigue behavior of the polycrystal. The modification of the mesoscopic criterion by taking into accountintragranular heterogeneities (with the standard deviation per grain of mechanical quantities) is discussed

Abstract:

Cette étude vise à étudier l'influence de la microstructure, de la rugosité et des défauts de surface sur le comportement en fatigue à grand nombre de cycles (FGNC) d'un acier inoxydable 316L obtenu par fabrication additive (FA). Composée d’un volet expérimental et d’un volet numérique, elle est motivée par le fait que les matériaux issus du procédé de FA présentent souvent un état de surface et une microstructure très distincts des couples procédés de fabrication / matériaux conventionnels. Afin de clairement identifier le rôle joué par chacun des facteurs influents sur la réponse en fatigue, différentes techniques de caractérisation (Profilométrie, EBSD, Tomographie RX, dureté …) sont employées et permettent de mettre en évidence un niveau de rugosité important après fabrication ainsi que des textures morphologiques et cristallographiques marquées. Pour ce qui est du comportement sous chargement mécanique, des essais cycliques à déformation totale imposée mettent en évidence un écrouissage cyclique avec durcissement puis adoucissement. Une importante campagne d’essais en fatigue est conduite sous différents modes de chargement (traction, flexion, torsion) et pour différentes configurations d’état de surface (brut de fabrication, poli). L’analyse des faciès de rupture fait apparaître le rôle prépondérant joué par les défauts de type « lack of fusion » sur les mécanismes d’amorçage en surface des fissures de fatigue. Un diagramme de type Kitagawa-Takahashi est construit à partir de l’observation de la taille des défauts à l’amorçage et le rôle des amas de défaut est clairement démontré. L’étude numérique comporte deux parties distinctes avec, d’abord, un travail préliminaire relatif à la construction d’une méthode non locale adaptée à la prise en compte des effets de microstructure en fatigue dans le cas d’un acier 316L corroyé. A partir des données collectées lors de la campagne expérimentale portant sur l’acier SLM 316L, un modèle d'éléments finis tenant compte de la rugosité, des défauts et de la microstructure est construit. Les calculs sont conduits en utilisant un comportement de type élasticité cubique associé ou pas à de la plasticité cristalline. À l'aide d’une approche faisant appel à la statistique des extrêmes, les résultats des simulations EF sont analysés de manière à quantifier les effets respectifs de la rugosité de surface, de la taille et morphologie des grains, de la texture cristallographique et des défauts
This study aims to investigate the influence of both the microstructure and surface defects on the high cycle fatigue (HCF) behavior of a 316L stainless steel obtained by additive manufacturing (AM). Surface defects and microstructure are dominant factors of fatigue behavior, while the AM materials often exhibit distinguished surface state and microstructure compared to conventional materials. The current study begins with an investigation of the material properties that are related to fatigue behavior. Microstructure observations of the powder and fabricated specimens are undertaken. Profilometry and tomography analyses make the inherent defects visible. The hardness, elastic behavior and elastic-plastic behavior are studied via mechanical tests. Then, load-controlled fatigue tests concerning different surface-treated specimens under different loading types are conducted. To reveal the mechanism of fatigue failure in the studied specimens, a comprehensive fractography analysis is carried out. Experimental research reveals the weakening of fatigue strength due to lack-of-fusion defects. Yet, the effect of the microstructural attributes is difficult to evaluate without numerical tools. A preliminary numerical study about the application of the non-local method in an explicit microstructure sensitive model is undertaken to complement the microstructure-sensitive modeling framework. Based on the data collected in the experimental campaign, a finite element model that can take into consideration of the defects and the microstructure of the SLM SS 316L is built up. Finite element analyses are performed with both cubic elasticity and polycrystal plasticity constitutive laws. With the help of the statistical method, the results from the FE model are used to quantitatively assess the influence of surface roughness and microstructural attributes on the fatigue performance of SLM SS 316L

Abstract:

Dans les dernières années de sa vie, Edmond de Goncourt projette de réaliser un livre sur L’Art japonais du XVIIIe siècle : il souhaite y inclure les monographies de treize artistes japonais. Finalement, la mort de l’écrivain interrompt son projet et seuls deux volumes seront publiés : Outamaro (1891) et HokousaÏ (1896). Dans le Journal des Goncourt, certains parmi les treize artistes destinés à être étudiés sont évoqués ; on peut donc imaginer quelques aspects de la suite du projet. En ce qui concerne la genèse des deux monographies accomplies, elle peut être examinée en s’appuyant sur les documents suivants : le Journal de Goncourt ; sa correspondance ; certains fragments de ces deux monographies parus avant la publication de leur édition originale et ces éditions originales elles-mêmes. Ces documents révèlent la persévérance avec lequel Goncourt récolte les informations et élabore son texte. Ce travail acharné portera ses fruits
In his later years, Edmond de Goncourt planned to publish a series of works on the 18th-century Japanese art. He intended the work to be composed of the studies on thirteen Japanese artists. However, Edmond only published two studies: Outamaro (1891) and Hokousaï (1896). In fact, the death of Edmond interrupted his project. Anyway, in the Journal of Goncourt, certain persons of the thirteen artists to study are mentioned; therefore, we can imagine various aspects on the rest part of his plan. Besides, as to the formation of the accomplished two studies, we can make a research by referring to the following documents: the Journal de Goncourt; his correspondence; the first edition of the two studies, along with their certain parts previously published. These documents reveal the following: Goncourt collected with zeal much information; the writer persevered in his elaboration of text; the fruits of his efforts had a favorable reception

Pin-up images have played an important role in American culture, in both their illustrated and photographic configurations. The pin-up is viewed as a significant representational cultural artifact of idealistic and aspirational femininity and of consumerism and material wealth, especially reflective of the mid-twentieth century period in America spanning the 1930s to the 1960s. These images not only reflect great shifts in social mores and women’s social status, but also affected changes in both areas in turn. Furthermore, pin-up images internationally circulated in magazines, advertising and promotional material, contributed to the manner in which America was idealized in Europe and beyond. Crucially, they influenced how an eroticized and glamorous, yet unrealistic, example of femininity came to be generalized as a desirous model of femininity. In recent years there has been vital, though limited, scholarly research into the cultural and social impact of pin-up imagery, to which this thesis adds to. This thesis takes a genealogical approach, charting the development of popular female-centric “pin-up” imagery in America since the 1860s and up to the 1960s, and its resurgence since the 1980s onwards. In doing so this thesis aims to provide a social, political and cultural context to the emergence of a specific archetypal sexualized femininity, with the aim of challenging the tendency to dismiss sexualized imagery as “anti-feminist” or as trivial. Toward that end, I examine the complexity of intentions behind the production of “pin-up” images. In taking this revisionist approach I am better able to conclusively analyze the reasons for the resurgence and reappropriation of pin-up imagery in late-twentieth- and early-twenty-first-century popular culture, and consider what the gendered cultural implications may be.

Abstract:

Chapter Five examines the value of a college degree, taking as its focus the recipients of retroactive diplomas awarded to Nikkei who were wrongly forced from high schools and institutions of higher education after the bombing of Pearl Harbor. Well into their 80s and 90s, these individuals stand to gain nothing material or economic from such action, and yet they have pursued it vigorously. No less important, so have a number of activists, most notably Mary Kitagawa, who helped persuade the University of British Columbia to award degrees to students it had expelled in 1942. The value of education, this chapter argues, lies less in its economic or even intellectual promise than in its political and social potential, particularly when thought of in terms of embodiment.

Abstract:

The useful life of a steam turbine and the establishment of turbine outage schedules are often determined by corrosion fatigue to the low pressure (LP) blades in the phase transition zone (PTZ). Developing an effective corrosion damage prediction methodology is an important step to successfully reduce the number of unscheduled steam turbine outages. Tests with dual certified 403/410 12% Cr martensitic steel were performed to quantify the influence of corrosion pits on the fatigue life during testing in environments that are comparable to operational conditions. Threshold stress intensity factors ΔKth and fatigue limits Δσ0 were determined in air and two aqueous solutions. Additionally, stress-life tests were performed with pre-pitted specimens in air and aqueous solutions. The data for transition from a pit-to-a-crack have been correlated using the Kitagawa Diagram. This presentation of the data relates the steady stress, cyclic stress and pit width to the prediction of fatigue failure. Ultrasonic fatigue testing was an essential aspect of this program. This testing technique makes it possible to accumulate cycles at a rate of approximately 20 kHz. At this rate one billion (109) cycles are accumulated in less than 14 hours. One billion cycles has been used as the definition for non-progressive crack or specimen run-out life. All of the data for the survival and failure stress intensity factor was well represented by the El Haddad refinement to the Kitagawa Diagram. Based on these test results a comprehensive methodology has been developed to quantify the risk of corrosion-fatigue failure at a pit.

Abstract:

A problem with fracture mechanics (FM) based fatigue analysis is that reliable information on initial crack/flaw size is often hard to obtain. Also, FM method can’t be applied directly to welded joints with relatively small initial flaws and long crack initiation life. This paper proposes a novel probabilistic FM method based on the equivalent initial flaw size (EIFS) concept. The initial crack size is substituted with EIFS to take both the crack initiation and propagation life into account. Three methods are tested to obtain mean value of EIFS: calibrating to S-N curves, Kitagawa-Takahashi (KT) diagram and fitting to test data. The obtained EIFSs are evaluated by comparing the predicted fatigue lives and crack evolutions with S-N curves and test crack evolution data. The suggested procedure is to derive the mean value of EIFS from S-N curves and the coefficient of variation from KT diagram.
