Abstract

After reviewing the phenomena of martensitic phase transformation in shape-memory alloys, the conventional models that take into consideration viscosity-like and capillarity-like response are investigated for vanishing "dissipative effects". It is shown that they do approach the fully conservative case. Experimental evidence indicates that the response is rate independent and thus a model incorporating a phenomenological rate-independent plasticity-type dissipation related with an activated phase-transformation process is investigated.
