Abstract : Quite amazingly, materials of a certain class popularly named as smart materials are capable of responding to an external stimulus. Shape memory effect is the property of some of these material to gain back its original shape when activated with suitable stimulus. Shape memory alloys (SMAs) are metals, which exhibit two very unique properties, pseudo-elasticity, and the shape memory effect. The polymers which exhibit shape memory effect are called shape memory polymers. A shape memory composite (SMC) can be created by combining two or more materials involving at least one shape memory material. The presented work aims at the development of a mathematical constitutive model for a SMC of SMA wires in SMP matrix. The mathematical model has been developed using the rule of mixtures for composites and the material property curves have been generated for the SMC for various thermo mechanical loading and unloading cycles using Matlab. © 2019 Elsevier Ltd.
