Influence of auxeticity on the processes of elastic deformation in a single crystal VZhM8 in the direction [011]

Abstract

Abstract The study of deformation processes in a cylinder made of monocrystalline heat-resistant nickel alloy VZHM8. Different variants of the orientation of the crystallographic axes of a single crystal of a VZhM8 nickel alloy relative to the axis of symmetry of the cylinder when it is shocks an rigid wall (Taylor test) are considered. It is shown that if the [011] direction coincides with the direction of shock loading of the cylinder, the initially circular sections of the cylinder turn into ellipses until the moment of rebound, which is explained by the influence of the negative Poisson’s coefficient.
