On geometry and continuum thermodynamics of movement of structural defects

摘要: Abstract A thermodynamic theory of the movement point, line and surface defects is considered at finite deformations. This based on balance laws for crystal defects. The together with well-known mass, momentum, moment energy entropy have been utilized to find driving forces acting Some derived formulae are well-known, e.g. Peach-Koehler formula, nevertheless, many new relations obtained, osmotic flux due force a grain boundary found as needed jump in density across moving discontinuity surface. Using problem constitutive modelling defect considered. elastic behaviour materials structural determined by equation imposed free density. takes into account strain, densities temperature. plasticity described vector equations stated between velocities respective forces.
