弹塑性力学 Mechanics of Elasticity and Plasticity （Teaching Papers） 林高用 Lin Gao-yong （Ph.D., Professor） School of Materials Science and Engineering, CSU 2010.5 Self-introduction Gao-yong Lin（1966.9—），Ph.D., professor，department of materials processing, school of materials science and engineering, CSU Graduated from mechanical department, Xiangtan University in 1989.6 Post-graduated from Institute of Metals Research in 1995.7 Started My Teacher Career from 1995, and Have Taught This Course for 12 years Major in Materials Working, esp. in Dies Design and Simulation Corresponding: 0731O） E-mail: gylin6609@ Opening Remarks 1．About this course Mechanics of elasticity and plasticity is an important branch of solid mechanics, including elastic mechanics, plastic mechanics and fracture mechanics. 2. About teaching Teaching in the class,in English as much as possible. Some interesting questions will be discussed in details. 3.About studying Presenting the class; studying after class,stress on understanding rather than memorizing.Study it not just for examination. 4.About checking and test presence and homework: 10-20% final test: 80-90% Warning: who is absent for 5 or more than 5 times will be excluded from the final examination. We exam what we have taught;and we teach what we will exam.
