Outline and Purpose of the Course	To solve the global warming problems, weight reduction of transport equipment is one of the essential issues to be accomplished. However, this effort, in turn, yields technical difficulties in plastic forming processes, such as utilization of light-weight materials and application of novel forming processes. Therefore, nowadays it is indispensable to use numerical simulations for prior prediction of formability. The objective of this lecture is to understand the framework and basic formulations of numerical techniques used for optimization of forming processes. Specifically, the fundamental and applied theories of nonlinear finite-element methods and associated techniques are described.
Course Goals	1. To understand the framework and basic theories of nonlinear finite-element methods and associated techniques used for plastic forming processes. 2. To develop a linear finite-element method program and to understand the effect of numerical factors on simulation accuracy using the developed program. 3. To improve an ability to resolve problems actively on the basis of literature survey and related discussion through reporting assignments.
Schedule and Contents	This lecture describes mainly the basic formulations and applications of finite-element methods for plastic forming processes. Specifically, basic governing equations, numerical techniques and programming are explained. These issues are linked effectively through some simulation examples. Moreover, cutting-edge topics will also be described. This lecture is preferable for students who already learned fundamentals of elasto-plasticity and programming. However, because students in Graduate school of Energy Science have a wide variety of educational background, the lecture will start from the very beginning of the basic issues. The lecture plan is as follows. Note that the weeks provided in the bracket【】is only as a guide: this will be subjected to change depending on students' level of understanding, and additional descriptions as well as assignments will be given to maintain a certain level of understanding if necessary. (1) Fundamentals of plasticity and constitutive equations 【3 weeks】 (2) Formulation of elastic finite-element method and case studies 【4 weeks】 Finite elements Principle of virtual work and its discretization Case studies (3) Formulation of elastoplastic finite-element method 【7 weeks】 Basic framework to solve nonlinear finite-element method Material nonlinearity Geometrical nonlinearity Contact nonlinearity (4) Latest topics on numerical simulation techniques 【1 week】
Evaluation Methods and Policy	A few reports will be assigned during the semester. The grade will be evaluated on the basis of assignments (50%) and a student's class performance (50%). Note that the following issues should be satisfied to obtain credits: (1) To attend the lecture at least twelve weeks. (2) To submit all assignments properly.
Course Requirements	This lecture is preferable for students who already learned fundamentals of elasto-plasticity and programming.
Study outside of Class (preparation and review)	Preparation and review of the lecture are mandatory. A few weeks will be allowed to prepare each report, in which self-schooling is necessary.
Textbooks	Textbooks/References	Reference materials will be announced and/or provided if necessary.
References, etc.	Reference materials will be announced and/or provided.
