Shape Memory: Heterogeneity and Thermodynamics

摘要: Shape memory (SM) of some mechanical systems is a very useful and widely used property. In broader sense, this term relates not only to the special ‘shape materials’, but also all elastic bodies, springs, bi-metals, generally many actuators, such as thermostats others. The aim our contribution show that these or materials have one common factor: at least thermoelastic continuous substructure. Some are composed substructures, e.g. two in case bi-metals. system works without dissipation energy. On other hand, if taking into consideration spongy bone, tendons cartilage, viscous constituent, ensures energy cases dangerous impacts, present material. But even here, material contains substructures collagen elastin ensure SM. Similar situation found shock-absorbers.
