| Abstract: | In this paper,the procedure and outline to develop Duncan-Chang model in ANSYS by using APDL are proposed and implemented.The numerical example is also solved and compared with conventional triaxial compression test data.All numerical results show that it is possible to accomplish some complex stress-strain analysis for soil engineering.Meanwhile,there are some advantages of faster convergence,higher precision and more conveniently preprocessing-postprocessing. |
