Introduction Shape recovery in shape memory alloys (SMAs) occurs during a reverse martensitic transformation from martensite to austenite phases. WebbShape Memory Alloys (SMAs) are part of the smart materials [14]. The SMAs are able to „remember‟ a shape constituted in advance [15]. This shape is the permanent shape. SMAs sense an external stimulus and respond to it by changing their physical properties which results in a deformation or deflection of the structure [11]. how to senior proof a home
