3.1 Thermoplastic energy dissipation

Dissipated energy. Stored energy
During plastic deformation, a large proportion of the mechanical energy supplied is transformed into heat. In metallic materials, the physical origin of this dissipation is explained by the movement of dislocations in the crystal lattice. The rest of the energy supplied is stored in the material. For a plastic deformation varying from 0 to ε p , let W p be the mechanical work supplied and ...
