In this paper, via experimental results of ultrasonic wave velocity changes and FEPM simulations of slip system under the pure shear plastic deformation of a pure Aluminum single crystal, the authors verify that the ultrasonic longitudinal wave velocity depends upon the development of point defects caused by intersected cross slip among dislocations and also examine the correlation of the point defect dependence of the longitudinal wave velocity with the elastic stiffness degradation due to plastic deformation damage which is closely related to the deformation instability mechanism.
