Effect of machined surface condition on fatigue strength of Ni based superalloy Alloy718 (2nd report, investigation of the residual stress relaxation using crystal plasticity FEM)
In this study, the effect of machined surface layer on residual stress relaxation was investigated. In previous study, low cycle fatigue strength was affected by residual stress. However, residual stress relaxation was complex because local plastic strain occurred by stress near yield stress. Also,...
