Abstract

Abstract

Under the hypothesis that the stress components of crack-tip fields are only the functions of θ,the differential equations of plane-stress crack-tip stress fields for orthotropic perfectly-plastic materials are obtained by using Hill's yield condition and equilibrium equations.By combining the general analytical expression with the numerical method the crack-tip stress fields for orthotropic perfectly-plastic materials for plane stress are presented.
