This study discusses the evolution of loading surface associated with the phenomena of ultrasonic
temporary softening and ultrasonic residual hardening and residual softening registered in the
experiments for plastic deformation of aluminum and titanium in the ultrasonic field. The aim is
to model these phenomena in terms of the synthetic theory of irrecoverable deformation. We
extend the flow rule relationships by two terms based on microstructural processes occurring in
ultrasound-assisted deformation. This study discusses the evolution of loading surface associated with the phenomena of ultrasonic
