In this paper we analyse numerically thermomechanical behaviour of a sandwich-type actuator where a shape memory alloy layer is located between two oppositely doped semiconductors. The mathematical model for this analysis is based on a coupled system of partial differential equations with constitutive equations taken in the Falk form. The system is solved using an efficient differential-algebraic solver and computational results describing thermomechanical fields in such devices are presented.
