英文摘要：

According to the general anisotropic viscoplastic constitutive relation theory, we get the constitutive relation and control equations of the combined stress wave in the anisotropic viscoplastic plate. The finitedifference method is used to study the propagation and the evolution rule of the combined stress wave in anisotropic viscoplastic plate under the combined loadings. The effects of some viscoplastic parameters and impact slope angle on the propagation and evolution rule of the combined stress waves are analyzed, and the reasonable explanation about some new phenomena is given.
