Fatigue life prediction under variable loading based on a new damage model devoted for defective material

Fatigue life prediction under variable loading based on a new damage model devoted for defective... This article presents a fatigue damage cumulative model under variable loading devoted for defective materials. The multiaxial stress amplitude is reported to the equivalent stress by combining it with the S–N curve and an algorithm to evaluate the damage model. The proposed model is connected cycle by cycle with the Wöhler curve and it takes into account the history of loading. An application has been carried out on a C35 low alloy steel containing defects. The results of the model are compared with the experimental results made on this context and those computed by the most frequently used damage model in fatigue (Miner’s model). It has been demonstrated that the proposed model presents a good prediction of the experimental results, allows a better fatigue damage prediction than the widely used Miner rule, and can be used as an interesting and a powerful engineering prediction for industrial users. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png The International Journal of Advanced Manufacturing Technology Springer Journals

Abstract

This article presents a fatigue damage cumulative model under variable loading devoted for defective materials. The multiaxial stress amplitude is reported to the equivalent stress by combining it with the S–N curve and an algorithm to evaluate the damage model. The proposed model is connected cycle by cycle with the Wöhler curve and it takes into account the history of loading. An application has been carried out on a C35 low alloy steel containing defects. The results of the model are compared with the experimental results made on this context and those computed by the most frequently used damage model in fatigue (Miner’s model). It has been demonstrated that the proposed model presents a good prediction of the experimental results, allows a better fatigue damage prediction than the widely used Miner rule, and can be used as an interesting and a powerful engineering prediction for industrial users.
