The Numerical Simulation of the Crack Elastoplastic Extension Based on the Extended Finite Element Method
In the frame of the extended finite element method, the exponent disconnected function is introduced to reflect the discontinuous characteristic of crack and the crack tip enrichment function which is made of triangular basis function, and the linear polar radius function is adopted to describe the...
