abstract:
In this paper,the 3D numerical simulation of compression process of Ti 6Al 4V titanium alloy shear-compression specimen(SCS)was carried out on ABAQUS software,and the mechanical response of compression-shear specimen under static and dynamic loading was studied.The influence of the geometric parameters(length to diameter ratio,root radius and thickness)of the SCS specimen on the analysis of the experimental results of the separated Hopkinson pressure bar(SHPB)was analyzed,and the feasibility of obtaining the yield surface of the material by using the SCS specimen was discussed.The results show that the geometric parameters had an effect on the analysis of SHPB experimental results.Increasing the aspect ratio of SCS decreased the dynamic force balance ability during loading.Under the premise of dynamic force balance,SCS specimen obtained effective dynamic and static yield surface,which can be used to study the yield criterion of materials.
