Finite Element Analysis on Crack Tip Deformation Behavior under Mode-II Loading in Single Crystal Superalloy

Article Preview

Abstract:

Crack tip deformation behavior of single crystal superalloy under mode-II shear stress condition was evaluated by crystal plasticity finite element method by applying Eshelby’s inclusion theory to express the relation between microscopic and macroscopic stress/strain character, and the influence of γ/γ’ microstructure and anomalous temperature dependence of yield strength in γ’ phase on crack tip deformation behavior was studied
