【Abstract】 In this paper we extended the two-dimensional linear strain joint elements of the rock mechanics to the three-dimensional nonlinear interface elements. The element stiffness matrixes developed in this paper can be used in the coupling mechanic problems of two kinds of materials with the customary three-dimensional nonlinear isoparametric elements.更多还原
