Abstract:
Für den Ermüdungsnachweis und die Bestimmung der Restlebensdauer bei stählernen Straßenbrücken nach Eurocode kann anstatt eines komplexen Lastmodells mit mehreren Fahrzeugtypen ein vereinfachtes Lastmodell, das nur aus einem Einzelfahrzeug besteht (ELM3), angewendet werden. Die tatsächliche komplexe Betriebsbeanspruchung wird dann durch sogenannte Schadensäquivalenzfaktoren l erfasst, die jedoch im Eurocode auf Stützweiten sowie Einflusslinienlängen L > 10 m beschränkt sind.   In diesem Beitrag werden nun neue Schadensäquivalenzfaktoren l für die maßgebenden Detailpunkte von orthotropen Fahrbahnplatten vorgestellt, die primär für die Anwendung bei Bestandsbrücken geschaffen wurden. Dazu wurden mehrere repräsentative orthotrope Fahrbahnplatten untersucht, unter Ansatz des komplexeren Ermüdungslastmodells ELM4, das aus fünf Fahrzeugtypen besteht. Daraus konnten dann die Schadensäquivalenzfaktoren l für das Lastmodell ELM3 abgeleitet werden.

Abstract:
In this paper, the frictional contact problem of a homogeneous orthotropic material in contact with a wedge-shaped punch is considered. Materials can behave anisotropically depending on the nature of the processing techniques; hence it is necessary to develop an efficient method to solve the contact problems for orthotropic materials. The aim of this work is to develop a solution method for the contact mechanics problems arising from a rigid wedge-shaped punch sliding over a homogeneous orthotropic half-plane. In the formulation of the plane contact problem, it is assumed that the principal axes of orthotropy are parallel and perpendicular to the contact. Four independent engineering constants , , , are replaced by a stiffness parameter, , a stiffness ratio, a shear parameter, , and an effective Poisson’s ratio, . The corresponding mixed boundary problem is reduced to a singular integral equation using Fourier transform and solved analytically. In the parametric analysis, the effects of the material orthotropy parameters and the coefficient of friction on the contact stress distributions are investigated.

Abstract:
In this study, the effects of orthotropy ratio and plate length on the stress concentration factor for orthotropic plates with a centred circular opening under the action of uniaxial tension loads are investigated by use of the finite element method. This work demonstrates that the stress concentration factor depends on the length of the member in addition to other established geometric parameters. The value of the transition length between long and short plates is computed and reported as well. This study has shown that Tan's equation for a finite width orthotropic plate is accurate for a ratio of the opening radius to plate semiwidth of less than 0.35 for orthotropy ratios less than 50. A new concept is introduced, namely the transition ratio.

Abstract:
Within the framework of classical elasticity, the nonbuckled deformations are calculated for orthotropic, right circular, thin-walled cylinders under uniform load conditions. The principle direction of orthotropy follows parallel constant angle helices. Nondimensional system parameters involving four material constants and three loading conditions (internal pressure, longitudinal load, and pure torque) are identified. Through parametric studies deformation patterns are calculated that are unique to orthotropy. Numerical examples illustrate that the proper selection of cylinder orthotropy can lead to designs with optimal deformations or load-carrying capacity. Results may be used for the design of robotic actuators driven by internal pressure.

Abstract:
Shape intrinsic orthotropy may be thought of as the type of elastic material symmetry possessed by the wood tissue of a tree. Each year’s new growth rings form a laminate around a central core. The axes of material symmetry lie in the directions tangent and normal to the growth rings or laminates and along the axis of the cylinder. Let Gtz denote the linear elastic orthotropic shear modulus associated with the axial and tangential directions, the tangent plane of a laminate. It is shown here that, for a certain class of elastic cylinders with shape intrinsic orthotropy, the solution to the torsion problem is the same as the solution to the torsion problem for the isotropic cylinder of the same shape if the isotropic shear modulus G were replaced by the orthotropic shear modulus Gtz.

The analysis of the stress state of a flexible orthotropic shell under the influence of a time-varying mechanical force and a time-varying external electric current is performed, taking into account the mechanical and electromagnetic orthotropy. The effect of thickness on the stress-strain state of the orthotropic shell is investigated. The results obtained indicate the influence of thickness on the deformation of the shell and the need to take this factor into account in the design schemes.

Abstract:
Le développement de nouveaux matériaux pose le problème de la connaissance de leurs constantes élastiques. Les méthodes de mesure des constantes élastiques sont nombreuses, mais ne permettent que très rarement de déterminer simultanément et de façon non destructive un grand nombre des composantes du tenseur des rigidités élastiques. Grâce l'essor des outils de calcul numérique et de traitement du signal, une nouvelle méthode est développée, basée sur l'analyse du comportement dynamique d'une plaque rectangulaire complètement libre à orthotropie spéciale. Deux modèles théoriques sont décrits selon que la plaque est mince ou épaisse conduisant aux équations aux dérivées partielles du mouvement et à l'expression des conditions aux limites. La résolution en terme de fréquences propres et modes propres de ces équations n'est pas simple, et par souci d'économie de temps calcul, une méthode semi-analytique originale est développée: il s'agit de la méthode dite de superposition qui permet de décomposer un problème qui n'admet pas de solution analytique, en deux sous problèmes dont la solution peut être décrite grâce à des développements en séries trigonométriques. Par ailleurs, un dispositif expérimental est mis au point, permettant, grâce à une bonne simulation des conditions aux limites complètement libres et à l'utilisation d'une métrologie sans contact, de déterminer avec précision les fréquences propres et modes propres d'une plaque. Sachant calculer théoriquement et mesurer expérimentalement les fréquences propres de la plaque, un algorithme est développé afin de déterminer les quatre ou six constantes élastiques (selon qu'elle est mince ou épaisse) régissant au mieux au sens des moindres carrés son comportement dynamique. Finalement, des résultats expérimentaux valident la méthodologie proposée et montrent sa précision et sa sensibilité

Full text
Abstract:
Les paramètres météorologiques jouent un rôle important sur le comportement des grands ouvrages d'art, les sollicitations induites par les actions thermiques pouvant être du même ordre de grandeur que celles dues au trafic. Ces actions sont caractérisées par deux paramètres essentiels : la température moyenne du tablier et le gradient thermique vertical linéaire équivalent. Pour ces facteurs, l'état des connaissances met en évidence l'insuffisance d'informations concernant les tabliers de pont constitués d'un caisson métallique orthotrope. Dans ce contexte, le pont de Normandie, ouvrage haubane de grande portée, a été l'objet d'une instrumentation importante permettant d'acquérir de nombreuses mesures qui sont traitées méthodiquement et interprétées dans ce travail. L’analyse donne, entre autres, les valeurs maximales des paramètres, à savoir 42°c pour la température moyenne et 24°c pour le gradient. Par ailleurs, une approche statistique originale permet de déterminer les valeurs cinquantennales des actions thermiques. Une modélisation numérique des échanges thermiques contribue à étendre l'étude à d'autres ouvrages et à déterminer l'influence des paramètres (température ambiante, rayonnement, vent et épaisseur du revêtement de chaussée). La confrontation des valeurs obtenues aux prescriptions de l'Eurocode (EC1) fait apparaitre de nombreuses différences. Nous avons aussi relie les paramètres thermiques aux effets mécaniques qu'ils engendrent en les confrontant aux mesures de déformation sur le caisson métallique. Les faibles contraintes générales auto-équilibrées engendrées par la distribution non-linéaire des températures autorisent la prise en compte du seul effet d'un gradient thermique vertical linéaire. Ce travail apporte des outils pour évaluer les actions thermiques a partir des paramètres météorologiques. L'ensemble des résultats constitue des informations très utiles pour des projets de ponts similaires et pour des mises à jour de la réglementation.

Abstract:
Ce travail présente une méthode d'estimation des caractéristiques de rupture différée, basée sur la théorie de schapery supposant un matériau viscoélastique orthotrope. En construction bois, la connaissance de la tenue à long terme est nécessaire au respect des règlements de construction. Les neuf composantes de la matrice des souplesses sont déterminées par des essais de fluage pour des durées comprises entre 1 et 6 jours. Les caractéristiques de rupture (facteur d'intensité de contrainte, taux de restitution d'énergie, vitesse de fissuration) sont recherchées par des essais de croissance stable de fissure. Le mode d'ouverture est réalisé pour les éprouvettes d. C. B. Le mode ii de glissement a nécessité la mise au point d'une nouvelle éprouvette permettant de stabiliser la propagation. Le comportement de l'éprouvette est modélise numériquement et met en évidence l'intérêt d'une géométrie a inertie variable. L’estimation de la durée de vie à partir de cette théorie fournit des résultats en accord avec la littérature.

Abstract:
La prévision de la répartition des déformations dans l'emboutissage des tôles et des limites de formage exige l'introduction dans les codes de calculs de lois décrivant avec précision le comportement plastique du matériau. Le but du présent travail est de proposer une modélisation de la surface d'écoulement plastique applicable aux matériaux orthotropes en contraintes planes. Cette modélisation est basée sur une représentation en coordonnées polaires de la surface d'écoulement dans l'espace des contraintes principales, et prend en compte l'orientation des axes principaux de contraintes par rapport aux directions principales d'orthotropie. Par rapport aux critères de plasticité classiques, la modélisation proposée a permis d'améliorer notablement la description des surfaces de plasticité expérimentales ou obtenues par un calcul d'homogénéisation. De même, elle a permis de mieux décrire les variations de la contrainte en traction uniaxiale en fonction de l'angle entre la direction de laminage et la direction de traction. Nous avons introduit le critère de plasticité proposé dans un code de calcul de prévision des limites de formage dans le cas d'une tôle isotrope transverse sollicitée en expansion. Les résultats montrent que la prise en compte d'améliorations réalistes concernant la forme de la surface de plasticité permet une meilleure prévision des limites de formage<br>The prediction of strain distributions and forming limits in sheet-metal forming process requires the use of accurate constitutive relations of the plastic behaviour in numerical computations codes. The aim of this work is to propose a modelling of plastic yielding that apllies to orthotropic materials under plane stress conditions. This modelling is based on a planar coordinate representation of the yield surface in principal stress-space, with account of the orientation of principal stress axes with respect to principal directions of orthotropy. In comparison with classical plastic yield criteria, the modelling allows us to obtain improved agreement with experimental yield surfaces or with results from homogenisation computations. It also allows an improved description of the variation of the uniaxial yield stress as a function of the angle between tensile axis and rolling direction. The yield criterion has been implemented in calculations of the forming limits of sheets with transversely-isotropic behaviour, in the stretching range. The results show that realistic improvements concerning the shape of the yield surface lead to a better prediction of the forming limits

Abstract:
A theoretical solution is given for the linearized buckling problem of an orthotropic toroidal shell with an elliptical cross-section under external pressure loading. The solution is based on the Sanders-Budiansky shell theory, and makes use of the harmonic differential quadrature method. Theory developed earlier for the buckling of orthotropic shells of revolution, and the vibration of orthotropic elliptical toroidal shells, is incorporated in the present work. Numerical results obtained from the solution are compared with results given in the literature, and good correspondence is generally observed. A parametric study is then conducted, covering a wide range of material and geometric parameters. Regression formulas are derived, indicating the variation of the buckling pressure with the degree of orthotropy of the material. Overall, the study introduces a new tool for the buckling analysis of elliptical toroidal shells, and extends the information available for orthotropic toroidal shells.

Abstract:
A methodology for performing two and three-dimensional fracture analyses in orthotropic materials using ANSYS software (“ANSYS”) is presented. The methodology makes use of analytically known crack tip fields in orthotropic materials and is implemented into a general purpose ANSYS macro. The ANSYS analysis, which takes into account the material orthotropy is performed in a regular manner by including the quarter point elements near the crack front. Then, in the post-processing module, the developed macro is run to associate the crack tip displacements with the orthotropic crack tip displacement fields to compute the mixed-mode stress intensity factors. Numerical examples are also presented that demonstrate application and validation of the procedure. These examples include an edge crack in an orthotropic strip and a surface crack in a transversely isotropic plate. The results show how the orthotropic fracture results may differ from those of isotropic fracture analysis. It is also shown that this difference can be dramatically big when the stress analysis is done using the orthotropic properties, whereas the fracture calculations are performed considering the crack tip fields for a crack in an isotropic material.

Abstract:
There is growing interest in the use of polymer composites with enhanced thermal conductivity for high performance fin arrays and heat sinks. However, the thermal conductivity of these materials is relatively low compared to conventional fin metals, and strongly orthotropic. Therefore, the design and optimization of such polymer pin fins requires extension of the one dimensional classical fin analysis to include two-dimensional orthotropic heat conduction effects. An analytical equation for heat transfer from a cylindrical pin fin with orthotropic thermal conductivity is derived and validated using detailed finite-element results. The thermal performance of such fins was found to be dominated by the axial thermal conductivity, but to depart from the classical fin solution with increasing values of a radius- and radial conductivity-based Biot number. Using these relations, it is determined that fin orthotropy does not materially affect the behavior of typical air-cooled fins. Alternatively, for heat transfer coefficients achievable with water cooling and conductivity ratios below 0.1, the fin heat transfer rate can fall more than 25% below the “classical” heat transfer rates. Detailed orthotropic fin temperature distributions are used to explain this discrepancy. Simplified orthotropic pin fin heat transfer equations are derived and validated over a wide range of orthotropic conditions.

Abstract:
High Cycle Fatigue (HCF) induced failures in aircraft gas turbine and rocket engine turbopump blades is a pervasive problem. Single crystal nickel turbine blades are being utilized in rocket engine turbopumps and jet engines throughout industry because of their superior creep, stress rupture, melt resistance and thermomechanical fatigue capabilities over polycrystalline alloys. Currently the most widely used single crystal turbine blade superalloys are PWA 1480/1493, PWA 1484, RENE’ N-5 and CMSX-4. These alloys play an important role in commercial, military and space propulsion systems. Single crystal materials have highly orthotropic properties making the position of the crystal lattice relative to the part geometry a significant factor in the overall analysis. The failure modes of single crystal turbine blades are complicated to predict due to the material orthotropy and variations in crystal orientations. Fatigue life estimation of single crystal turbine blades represents an important aspect of durability assessment. It is therefore of practical interest to develop effective fatigue failure criteria for single crystal nickel alloys and to investigate the effects of variation of primary and secondary crystal orientation on fatigue life. A fatigue failure criterion based on the maximum shear stress amplitude [Δτmax] on the 24 octahedral and 6 cube slip systems, is presented for single crystal nickel superalloys (FCC crystal). This criterion reduces the scatter in uniaxial LCF test data considerably for PWA 1493 at 1200F in air. Additionally, single crystal turbine blades used in the alternate advanced high-pressure fuel turbopump (AHPFTP/AT) are modeled using a large-scale 3D finite element (FE) model. This FE model is capable of accounting for material orthotrophy and variation in primary and secondary crystal orientation. Effects of variation in crystal orientation on blade stress response are studied based on 297 FE model runs. Fatigue lives at critical points in the blade are computed using FE stress results and the failure criterion developed. Stress analysis results in the blade attachment region are also presented. Results presented demonstrates that control of secondary and primary crystallographic orientation has the potential to significantly increase a component’s resistance to fatigue crack growth without adding additional weight or cost.

Abstract:
The eigenvalue problem of an orthotropy composite blade is formulated by employing the differential quadrature method (DQM). The Euler-Bernoulli beam model is used to characterize the orthotropy composite blade. The differential quadrature method is used to transform the partial differential equations of an orthotropy composite blade into a discrete eigenvalue problem. The Chebyshev-Gauss-Lobatto sample point equation is used to select the sample points. In this study, the effects of the fiber orientation, internal damping, external damping, inclined angle and the rotation speed on the eigen solutions for an orthotropy composite blade are investigated. The effect of the number of sample points on the accuracy of the calculated natural frequencies is also discussed. The integrity and computational efficiency of the DQM in this problem will be demonstrated through a number of case studies. Numerical results indicated that the differential quadrature method is valid and efficient for an orthotropy composite blade formulation.
