ABSTRACT: The paper aims to develop a model describing the
ultrasound-assisted pseudoelastic deformation of shape memory alloys.
Experimental results record that acoustic energy reduces the value of stresses
needed to induce pseudoelastic deformation (martensitic transformation). At the
same time, the ultrasound-assisted deforming develops with a more significant
strain hardening. The model presented here is based on the synthetic theory of
inelastic deformation. To catch the phenomena caused by acoustic energy, we
enter into the basic equation of the synthetic theory terms reflecting the
effect of ultrasound on the processes governing the peculiarities of
pseudoelastic deformation in the acoustic field. The analytical results fit
good experimental data.
