Abstract

Publisher Summary This chapter discusses the micro mechanics modeling for micro forming processes. In traditional metal forming processes, continuum mechanics-based FE techniques can be used for process simulation. However, in micro-forming processes, if the ratio of the minimum dimension of a micro-part and the grain size of the material is small, CPFE analysis has to be used, otherwise the important features of the forming of micro-parts cannot be captured. Crystal plasticity finite-element (CPFE) analysis can be carried out using existing commercial FE codes, such as ABAQUS: there is no need to generate special FE codes for this purpose. The main difficulties in the simulation of micro-forming processes using CPFE are: the creation of the CPFE model, which includes the generation of the micro-structures of materials, material orientations and the creation of an FE mesh within grains and crystal plasticity material models, which include the development and determination of micro-mechanics material models and the implementation of the models in commercial FE codes.
