本课程是面向力学专业高年级本科生开设的一门选修课。主要讲述塑性力学的基本概念和方法，主要内容包括应力分析和应变分析；屈服条件和加载条件；塑性状态下的本构关系；复杂应力状态下最简单的弹塑性问题等。该课程要求学生在掌握塑性力学中的基本理论和方法的同时还应具有运用所学理论处理和解决工程中相关问题的能力。学习本课程前，学生应具备材料力学和弹性力学等课程的基础知识。 Mechanics of Plasticity is an elective course，and for advanced undergraduates of Mechanics. The aim of this course is to provide a comprehensive introduction to the contemporary state of knowledge in basic plasticity theory and to its applications, including the physics of plasticity，yield criteria, flow rules and hardening rules, and constitutive theory, in addition to a representative survey of problems treated by classical methods, such as elastic-plastic problems; the problem discussed come from areas of interest to mechanical, structural, and geotechnical engineers, metallurgists and others. Students should have a basic knowledge of the courses such as Mechanics of Materials and Mechanics of Elasticity.
