Abstract

Abstract

Using dynamic finite element method, the propagation of stress waves in two-dimensional conically shaped stress-wave-amplifiers is analysed. The effects of geometrical factors, input-pulse shape and pulse rising time on amplifying multiplication and wave shape of transmission waves are discussed. The consistency between numerical results and experimental results based on Hopkinson bar is satisfactory. The numerical accuracy is inploved comparing with the characteristic method.
