Studies of the propagation of elastic and plastic waves in cubic single crystals

Abstract

Abstract The study of the elastic and plastic properties of a single crystal with cubic symmetry of mechanical properties under dynamic loading was carried out. In the work, the method of numerical simulation shows the effect on the output of an elastic precursor and a plastic compression wave of the orientation of the calculated coordinate system relative to the direction of loading. It is shown that the rotation of the calculated coordinate system by 450 around the axis of loading of the projectile and the target in the framework of numerical simulation of the process of shock loading affects the stress state of the target and the velocity profile of its rear surface. This is explained by the fact that in the plane of loading the elastic and plastic properties in a single crystal with cubic symmetry of properties change in accordance with the values of Euler angles.
