Overview
In this entry thermoplasticity of polycrystalline metalsis reviewed. First, the physical foundations of plastic deformation in metals are presented. Within this part microstructure of polycrystals is discussed presenting typical lattice geometries and explaining the crystallographic nature of plastic slip (dislocation motion), which takes place only on the selected lattice planes in the selected lattice directions. The way by which material parameters depend on temperature is indicated. A difference between deformation of material fibers and lattice directions is underlined. Then, the classical crystal thermoplasticity model is outlined. A large-strain framework is used since such models are often applied to supplementary analysis of metal-forming processes. The most common rate-independent and rate-dependent formulations are discussed. After formulation of a thermomechanical boundary value problem, the micromechanical models of polycrystals are presented. The phenomenon of...
