摘要：
Some of the main progress on the investigation of the mechanism of the wave formationin explosive welding at the Institute of Mechanics is summarized and otters’previous works are re-viewed.Our systematic experiments and analysis do not substantiate the theory of wave formationbased on Karman vortex-street analogy or Helmholtz instability.On the contrary,they show that materi-al strength insensitive to strain rate plays an important role.A simple hydro-plastic model is presentedto explain the main features regarding the interracial wave formation and to estimate the magnitude ofwave length.The result is in broad agreement with experiment.
