Probabilistic Fatigue Analysis
1995Fatigue is one of the most important failure modes to be considered in mechanical and structural design. It has been stated that fatigue accounts for more than 80% of all observed service failures in mechanical and structural systems. Moreover, fatigue and fracture failures are often catastrophic; they may come without warning and may cause significant

Wellhead Fatigue Analysis Method
Volume 1: Offshore Technology; Polar and Arctic Sciences and Technology, 2011Re-completion and re-drilling of existing wells and introduction of new large drilling rig systems are elements that have led to renewed focus on the fatigue capacity for existing and new subsea wells. Due to lack of applicable codes and standards for such fatigue calculations, a unified analysis methodology has been developed and described in a ...

Advanced fatigue reliability analysis
International Journal of Fatigue, 1991Abstract Factors in fatigue life prediction models can be treated as random variables reflecting inherent uncertainties in material behaviour and loading. Given the probability distribution of these factors, U , the distribution of life, N , is derived when a reliability analysis is performed.

Fatigue striation spacing analysis
Materials Characterization, 1994Abstract Fatigue crack growth in ductile materials produces features, called striations, on a fracture surface, which can aid greatly in understanding conditions associated with the fracture, including the number of stress variations that produced the fracture.

This paper shows the implementation of a simplified method for damage and life estimation of a 1.5 kW wind turbine blade with an aerodynamic stall limiting system. The findings of this research contribute to advancing the field of wind energy by providing a streamlined and efficient approach to address blade fatigue issues, ultimately promoting the ...

Welded Pipeline Fatigue Analysis
1994This case study shows the importance of considering welding flaws in pipelines that may be subjected to cyclic pressures. The case study will demonstrate that the ASTM specifications currently used to purchase welded pipe do not ensure adequate safety for cyclic loading.

Fatigue and Inelastic Analysis
1988Evaluation of fatigue damage necessitates calculation of the strain range. Current design rules provide realistic evaluations in the absence of elastic follow-up but very conservative evaluations when shakedown is not obtained. It is proposed to include spring effect in the strain range calculations using elastic analysis to reduce the need for ...
