Fatigue constrained topology optimization
TL;DR: In this paper, a probability based high-cycle fatigue analysis is combined with principal stress calculations in order to find the topology with minimum mass that can withstand prescribed variable-amplitude loading conditions for a specific life time.

Re-design of a failed clutch fork using topology and shape optimisation by the response surface method
TL;DR: In this article, a failed clutch fork was completely re-designed using topology and shape optimisation approach, and a new design proposal was determined with the topology optimization approach and then design optimization by response surface methodology was effectively used to improve the new clutch fork design.

Evolutionary topology optimization of continuum structures considering fatigue failure
TL;DR: In this paper, a simplified topology optimization was developed to prevent fatigue failure based on the bi-directional evolutionary structural optimization (BESO) approach where the modified Goodman fatigue failure criterion was applied directly in the sensitivity analysis.

Optimal vehicle suspension characteristics for increased structural fatigue life
TL;DR: In this paper, an experimentally validated non-linear seven degree-of-freedom mathematical model of the test vehicle is constructed for the use in sensitivity studies to determine the robustness of the optimal suspension characteristics and their sensitivity to vehicle payload variation.

Multi-objective robust design optimization of fatigue life for a welded box girder
TL;DR: A robust optimization method is presented based on a dual surrogate modelling and multi-objective particle swam optimization algorithm to reduce the scatter of fatigue life for welded structures and indicated that the procedure improved the robustness of the fatigue life.

High cycle fatigue and a finite element analysis
TL;DR: In this article, a finite element method was developed for high cycle fatigue under periodic constant load systems, which can be used for finite element-based CAD design of structural components, and the authors described a CAD system that can be derived from this analysis.

Numerial implementation of multiaxial high-cycle fatigue criterion to structural optimization
TL;DR: In this paper, modern multiaxial high-cycle fatigue criteria were investigated with respect to their application in structural optimization procedures coupled with finite element codes as a result of tests carried out for several fatigue criteria, the Dang Van hypothesis was used for the detailed numerical study.
