On the numerical implementation of the higher-order strain gradient-dependent plasticity theory and its non-classical boundary conditions
Finite element implementation of higher-order gradient plasticity theory is presented. Numerical implementation of higher-order boundary conditions at interfaces. Plastic strain gradients are calculated using weighted meshless method. Application to various size-dependent plasticity problems with surface effects. Special numerical treatment of a moving elastic-plastic boundary is proposed.
