摘要
In this work,the types of shock wave structure for hydro-elastoplastic model under compression are researched.The emphasis focuses on the theory of shock transition in the presence of elastic-plastic-fluid phase transition.As a result,in addition to the classical three-wave structure,two new shock wave patterns are found with the increase of loading strength.Several numerical tests are presented to verify the existence of the three types of wave structure.
