| Abstract: | According to the constitutive relation of rockmass of tensile fracture the non linear FEM program of tensile fracture analysis was developed, and the reasonability of this FEM model and correctness of the program was testified by using simple calculation examples. By adding this program in common elastic and elastoplastic FEM program the deformation characteristic of rockmass under tensile stress was presented. |
