图书简介
Crystal plasticity theory works at a small, usually microscopic scale. Dislocation Mechanism Based Crystal Plasticity: Theory and Computation at Micron and Submicron Scale provides a comprehensive introduction to the continuum and discreteness dislocation mechanism-based theories and computational methods of crystal plasticity at the micron and submicron scale. This volume grows from over 20 years of research and is a vital resource on continuous and discrete dislocation mechanisms-based crystal plasticity at the micron and submicron scale. The book consists of two parts. The first covers continuum dislocation mechanisms and includes the fundamental concept of conventional crystal plasticity theory at the macro-scale without size effect, strain gradient crystal plasticity theory based on Taylar law dislocation, mechanism at the mesoscale, considering size effects, phase-field theory of crystal plasticity and the application in modelling dislocations. In order to expand the crystal plasticity theory model, the application in nickel-base super-alloys is also illustrated. The second part describes discrete dislocation dynamic mechanism-based theory, and computation at the submicron scale, including single crystal plasticity theory, and discrete-continuous model of crystal plasticity with three-dimensional discrete dislocation dynamics coupling finite element method (DDD-FEM). Three kinds of plastic deformation mechanisms for submicron pillars are systematically presented. Further, dislocation nucleation and starvation at high strain rate, and temperature effect for dislocation annihilation mechanism, are described.
