Abstract
An extended finite element method is applied to predict residual strength of cracked thin sheet plates. Two kinds of middle tension M(T) testings different in initial crack direction are simulated for stable crack growth process based on a crack tip opening angle criterion or a cohesive crack model. Crack growth direction is determined from direction of the maximum principal stress at the crack tip. Material follows plane-stress J2 plasticity with linear isotropic/kinematic hardening. The residual strength and crack propagation path obtained by the extended finite element method are compared to experimental measurement and show reasonable agreement.
