Smart alloys examples
There are a number of types of smart material, of which are already common. Some examples are as following: • Piezoelectric materials are materials that produce a voltage when stress is applied. Since this effect also applies in a reverse manner, a voltage across the sample will produce stress within sample. Suitably designed structures made from these materials can, therefore, be made that be… WebShape memory alloys Vladimir Buljak, Gianluca Ranzi, inConstitutive Modeling of Engineering Materials, 2024 9.2Shape memory effect The ability of shape memory …
