2. Simulation of post-curing SMAC plate shape and snap-through behaviour using a simplified thermomechanical model of SMA wires 2.1 ECTE model of SMA thermomechanical behaviour The effective coefficient of thermal expansion (ECTE) model proposed by Turner et al. (2007) is based upon nonlinear thermo-elasticity and its fundamental feature is that the the non-mechanical (i.e., thermal and transformation) strains below the austenite start temperature (T
