Keywords: stress-based topology optimization, fatigue criteria.

Summary

This paper shows how the design of a structure can evolve when considering a stress-based topology optimization along with fatigue failure constraints. More precisely, fatigue failure is added in a stress-based topology optimization Matlab code by following the approach of the design of machine elements, i.e. based on S-N curves or fatigue criteria. The fatigue is introduced through weel-known criteria for high-cycle fatigue such as the Sines and Crossland criteria. The paper presents how these criteria can be formulated for a topology optimization problem. Numerical results for both criteria are successively compared and discussed. The character of fatigue failure in the optimization procedure is illustrated as well as some issues that have to be improved in future work.
