Aims
The purpose of this course is to introduce the basic theories and knowledge and general solution techniques of elasticity and plasticity, covering the theory of tress and strain, the introduction of stress-strain constitutive relation, the solution techniques in two-dimensional and three-dimensional boundary value problems of elasticity and plasticity, the energy principles and energy method of solution of solid continuum mechanics, and the elementary theory of classical Kirchhoff plate. As a basic branch of solid mechanics, it is intended to give graduate students sound foundations on which to build advanced courses such as thermal elasticity and plasticity, fracture mechanics, the theory of plates and shells, mechanics of composite materials, and the computational mechanics.
Intended learning outcomes
By studying this course and reading relevant Chinese version books, the students will be able to:
1) Understand and apply the basic theories, knowledge and solution in boundary value problems of elasticity and plasticity;
2) Understand and apply the energy principle and approximate solution method of solid mechanics;
3) Apply the theories, knowledge and solution skills to the study of analysis of stress and strain, fracture and strength problems, numerical methods for solid mechanics and advanced theories of elasticity and plasticity, and the design of effective structures in engineering.
