Webb7 nov. 2024 · Smart materials that have a great potential to achieve this goal are shape memory alloys (SMAs). These materials, under the influence of temperature stimuli, are capable of spontaneous and reversible changes of shape. This shape memory effect is due to thermoelastic martensitic transformation, which is accompanied by heat exchange. WebbWe’re the innovators in shape memory alloy smart materials. Our vision is the seamless integration of smart materials into a better everyday life. We work with businesses … 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]. theory of machines and mechanisms 5th
