Modeling of elastoplastic crack propagation using finite element method with adaptive mesh / Syifaul Huzni and Ahmad Kamal Ariffin

Modeling of crack propagation using adaptive finite element mesh is presented in this paper. An adaptive mesh is applied to analyze two-dimension elastoplastic fracture during crack propagation. Displacement control approach and updated Lagrangean strategy are used to solve the non-linearity In geom...
