Abstract
A numerical method is presented to analyze three-dimensional stress waves in an elastic/viscoplastic thick plate, when oblique impact is applied to the surface of the thick plate at various impact angles. For the numerical analysis, the finite difference method based on integration along the bicharacteristics is employed. From the numerical results obtained for various loading conditions, the effect of the impact angle on impact fracture is examined. It is also demonstrated that the dynamic behavior of the plate due to oblique impact can be examined in detail using this method.
