摘      要：Multilayer materials are widely used in military,automobile and aerospace *** this paper,the response of an explosion-welded Ti6Al4V/pure titanium with a flat interface to dynamic loading is *** SHPB apparatus is ***,the dynamic behaviour of a bimetal sample is explored with a DIC system coupled to the *** indicates that in the bimetal sample pure titanium is deformed and failed before *** stress curve of the sample shows two different peaks in a striker velocity higher than the 18.3 m/*** the incident wave encounters the interface of the Ti6Al4V/pure titanium sample,only a small fraction of the wave is reflected owing to similar *** the direct interpretation stress-strain curve is unreasonable in this case because of unhomogenised plastic *** micro structure of the sample is investigated after *** adiabatic shear band is formed in the pure titanium side before failure,and the interface of the sample remains intact under different loading *** FEM simulation result for the sample is in good agreement with experimental observations.
