摘要：

A proposed finite element model was described to address deformation of constant strain triangular elements as well as slip between the elements. This model has three degrees of freedom at every interior node. The constant slip between two elements depends only on the third degree of freedom. Hence the proposed model separates in two constituents, i. e. a classical and a slip part. The results of the proposed model are compared with those of the classical and the slip model, as well as the analytical results.
