摘要: A numerical method based on the virtual crack closure technique (VCCT) (Rybicki and Kanni- nen (1977)) in conjunction with finite element (FE) is presented to compute strain energy re- leaserates forcracks that kink. Themethod partitionsthe release rate provides an efficient means values of mode I (GI) II (GII ) at tip a kinking crack. The solution procedure shown be computationally effi- cient operationally simple, involving only nodal forces displacements near tip. Example problems cracks homogeneous mate- rial, layered two constituent material are illustratethe current approach. keyword: crack, tech- nique,
