Abstract
The present paper aims to model ultrasonic effects such as temporary softening and residual hardening. While temporary softening is observed during simultaneous action of mechanical forces and ultrasound, residual hardening manifests itself after switching off the ultrasound. The analytical description of these phenomena is conducted in terms of the synthetic theory of irrecoverable deformation. The model results show good agreement with experimental data obtained for the ultrasound-assisted compression of pure aluminum.
