Improved high cycle fatigue life prediction
WitrynaAbstract This study is based on continuum damage mechanics and constructs an improved macro–micro-two-scale model to predict the fatigue life of engineering … WitrynaHCF requires a high number of loading cycles to reach fatigue failure mainly due to elastic deformation. It has lower stresses than LCF, and the stresses are also lower than the yield strength of the material. HCF usually does not have macroscopic plastic deformation as large as that in LCF. The dominant strain in HCF is mainly elastic.
