Most metal parts and products are manufactured through metal plastic forming technology. Metal forming technology mainly includes forging, stamping, rolling, extrusion, drawing, et al. The typical characteristic of these technologies is that the metal workpiece undergoes permanent deformation by means of applied force so that the desired shape is obtained. The deformation analysis in metal forming process is based on plasticity theory and material science, and the corresponding results takes a great role as fundamental reference in the design of metal forming procedure and forming machines. The course of “Fundamental Mechanics in Material Processing” is therefore one of the key courses in study of materials processing engineering.The main topics of this course are:1.Strain and deformation analysis of metal forming process so that to provide theoretical bases for rationally designing billet or sheet profile, controlling the surface quality, and laying out the processing schedule.2.Stress and forming load analysis of metal forming process so that to provide theoretical bases for selecting machine capacity and preventing the product from undesirable residual stress.3.Prediction of metal microstructure evolution and its influence to the product mechanical properties so that to provide reference for controlling the inner quality of the product.For these purposes, the main theoretical bases that should be emphasized in this course are as follows:1.The description of large displacement deformation case, the formulation of stress and strain for nonlinear deformation behavior, and the governing differential equations and boundary conditions of these variables.2.Material plastic deformation behavior and constitutive relations, yielding criterion and stress-strain relationship for plastic deformation.3.Basic principle, especially the energy theorem, for metal plastic deformation, energy theorem based analysis method, such as upper bound method, rigid plastic finite element method, et al.4.Microscopic mechanism in metal plastic deformation, and product mechanical property control.
