Abstract: This encompasses finite element simulation and experimental investigations of the shape memory effect due to the presence of Cu-Al-Ni SMA particulate reinforcement in Al alloy matrix known as SMA composites. Simulation was accomplished using ANSYS where the prestrain was modeled by equivalent alterations in the expansion coefficient of the SMA particulates. The properties namely young’s modulus, poisson’s ratio and coefficient of thermal expansions were simulated and their predictions were compared with experimental data for as-cast and SME trained composites at different temperature loads known as ‘training’. An FEA and experimental investigation SMA composites properties allows assessment of the effect SMA volume fraction and shape memory effect at different temperatures. These outcomes shack light on the design of SMA reinforced composites.
