Abstract:

The Bagci, Gerber, Goodman, quadratic, and Soderberg diagrams are some of the diagrams proposed to serve as practical design tools for the design of ductile metals loaded in fatigue with positive mean and alternating stresses. However, all of these diagrams are either conservative, or have domains containing stress greater than yield strength of material. This paper presents the Clemson diagram, which has the same format as the aforementioned diagrams with the exception that the exponential power order varies with the material property. The Clemson diagram has a great potential to fit the expe

Abstract:

In many analyses of composite wind turbine blades, the effects of mean stress on the determination of damage are either ignored completely or they are characterized inadequately. An updated Goodman diagram for the fiberglass materials that are typically used in wind turbine blades has been released recently. This diagram, which is based on the MSU/DOE Fatigue Database, contains detailed information at thirteen R-values. This diagram is the most detailed to date, and it includes several loading conditions that have been poorly represented in earlier studies. This formulation allows the effects

Abstract:

AbstractIn this paper I tackle the question of what basic form an analytical method for articulating and ultimately assessing visual representations should take. I start from the assumption that scientific images, being less prone to interpretive complication than artworks, are ideal objects from which to engage this question. I then assess a recent application of Nelson Goodman's aesthetics to the project of parsing scientific images, Laura Perini's ‘The truth in pictures’. I argue that, although her project is an important one, her Goodmanian conventionalism produces a method of analysis tha

Abstract:

A new vibration-based fatigue testing methodology for assessing high-cycle turbine engine material fatigue strength at various stress ratios is presented. The idea is to accumulate fatigue energy on a base-excited plate specimen at high frequency resonant modes and to complete a fatigue test in a much more efficient way at very low cost. The methodology consists of (1) a geometrical design procedure, incorporating a finite-element model to characterize the shape of the specimen for ensuring the required stress state/pattern; (2) a vibration feedback empirical procedure for achieving the high-c

Abstract:

A method for constructing a modified Haigh-Goodman diagram for flawed components is proposed based on the approximation by El Haddad for the crack growth threshold diagram, taking into account the influence of the stress ratio on the fatigue limit of the unflawed material as well as on the linear-elastic crack growth threshold. The modified Haigh diagram uses a minimum of easily obtainable material parameters and permits an easy application of damage tolerant design concepts when dimensioning for infinite fatigue life.

This paper reports on recent fatigue data of interest to the wind turbine industry in several areas: (a) very high-cycle fatigue data; (b) refined Goodman Diagram; (c) effects of fiber waviness; and (d) large-tow carbon fibers. Tensile fatigue results from a specialized high-frequency small strand testing facility have been carried out to 1010 cycles in some cases, beyond the expected cycle range for turbines. While the data cannot be used directly in design due to the specialized test specimen, the data trends help to clarify the proper models for extrapolating from standard coupons to higher

Abstract:

Accurate prediction of lifetime is an increasingly important issue for wind turbine rotor blade materials. Coupon tests with the variable-amplitude standard loading sequences for wind turbines known as WISPER and WISPERX have indicated that the coupon lifetime can be overestimated by one or two orders of magnitude using conventional lifetime prediction formulations. In the actual design, this might be compensated for by conservative design factors covering other aspects such as environmental conditions. These conventional lifetime prediction formulations use Rainflow counting of the load histo

Abstract:

This dissertation is a study of a remarkable change that came about in the kind of drawings that architects used to present their work between the decades of 1960 and 1990. Drawings in this period, visually rich and compositionally complex, seemed to mark an entirely new sensibility towards their function; their goal seemed to be not so much to clearly depict the forms of a proposed building, but to instead focus on its conceptual aspects. In fact, in several cases, drawings seemed to be treated as graphic projects in their own right, over and above the work they presented. This trend was acco

Abstract:

A pragmatic approach for estimating cyclic stresses in rotating airfoils based on impulse testing with strain gauge sensors and application of simplified aerodynamic excitations is presented. The method has been successfully applied to determine the root causes of blade and impeller failures in gas turbines, steam turbines, and industrial compressors. The method provides guidance for quickly determining the natural frequency most responsible for a failure by analyzing experimental stress data at blade resonances, incorporating the Campbell diagram to evaluate frequency margins, and applying th

Abstract:

Possible alternative fatigue formulations to predict lifetime under variable-amplitude loading are investigated. Test results of WISPER and WISPERX variable-amplitude tests on a material representative for wind turbine rotor blades are used. All fatigue calculations are performed using Rainflow counting of the WISPER(X) load histories and employing the Miner summation. The formulation of the SN-curve and the constant-life diagram are varied. Commonly, a log-log SN-curve is used in combination with a linear Goodman constant-life relation.

This paper defines a probabilistic High Cycle Fatigue (HCF) assessment process for a fan or compressor Integrally Bladed Rotor (IBR). It identifies key design variables, how they are statistically modeled, the probabilistic integration technique, and the physics-based modeling process. It defines how previous eigensensitivity based reduced order models cannot be used for IBR assessment and validates an alternate approach. An autoregressive model accounts for correlation between IBR blade-to-blade variabilities. An approach is also defined to combine sector tuned stress variation and mistuning

Therefore, its validity was checked by performing a fatigue test programme involving strip specimens extracted from actual forged J-lay connectors. The effects of stress ratio and surface roughness on fatigue strength were investigated.

Abstract:

Accurate prediction of crack initiation life is of critical importance in designing turbo-machinery. To improve this accuracy, more sophisticated prediction techniques are required. A large number of materials have shown a correlation between low cycle fatigue initiation life and strain range, as represented by the well-known Manson-Coffin equation. Testing has shown that tensile mean stress has a negative impact on life. This effect has been noted for many years when applied to high-cycle fatigue, resulting in the use of Goodman or Haigh diagrams to account for the impact of both stress range
