Class Objectives
/Class Outline Students will learn the fundamental theory of engineering elasto-plasticity which includes various stress-strain responses of elastic-plastic materials, yield criterion, flow theory, several approaches for stress/strain analysis and finite element method oriented to structural design and metal forming simulation.

Class Schedule lesson1: Introduction: objective of theory of engineering elasto-plasticity and various stress-strain responses of elastic-plastic materials.
lesson2: Fundamentals of solid mechanics (1. stress equilibrium, strain compatibility condition).
lesson3: Fundamentals of solid mechanics (2. constitutive equation, boundary conditions for analysis).
lesson4: Energy principle (principle of virtual work).
lesson5: Theory of elasto-plasticity, yield criterion.
lesson6: Expression of work hardening.
lesson7: Plastic potential and associated flow rule.
lesson8: Various constitutive equations (yield functions and work-hardening rules)
lesson9: Various elasto-plastic problems (temperature and rate dependency, elastic-viscoplastic problem...)
lesson10: Elastic finite element method (1. element stiffness equation).
lesson11: Elastic finite element method (2. assembling and solving global stiffness equation).
lesson12: Elastic-plastic finite element method.
lesson13: Rigid-plastic finite element method.
lesson14: Applications of engineering elasto-plasticity (1. numarical simulation of metal forming process).
lesson15: Applications of engineering elasto-plasticity (2. design optimization based on finite element simulation).
