FEM Simulation shows that the inˉcreasing rate of the internal high pressure exerts different influences on the wrinkle's evolvement with the change of the combination mode of internal pressure and axial pressure.

In this paper, 3-dimension CAD technology is introduced into CWR field, process and die design scheme based on rolled pieces is presented, a corresponding CAD system is developed, as well as FEM simulation technology is used as the virtual test.

In consideration of the special structure of cut-off walls and their typical geophysical environment, the finite element simulation and physical model test were performed on their electric field to verify the feasibility of the transverse profile resistivity method applied to the inspection of the quality of cut-off walls and the characteristics of and condition for its application.
