Abstract:Hopkinson rupture is a typical tensile failure phenomenon caused by the reflection of the stress wave,while this phenomenon can not be simulated perfectly using finite element method at present.On basis of introducing the basic principle of numerical manifold method,this phenomenon is simulated with its computer program of numerical manifold method.The results of simulation are in agreement with that obtained by theoretical analysis,so numerical manifold method is proved to be effective in analyzing the problem of material failure.
