IntroductionThe elasticity is a branch of the solid mechanics. The task isto research the elasticity object's stress, deformation anddisplacement due to external force or change of temperature.This course shows the mathematics modeling process ofmechanics problems completely, and establishes the basicequation and boundary condition of the elasticity andproceeds to beg the solutions of some problems. Thefoundation of the elasticity basic equation lays a foundationfor further number methodThe elasticity is the foundation of studying plasticityfracture mechanics and finite element method3
3 The elasticity is a branch of the solid mechanics. The task is to research the elasticity object’s stress, deformation and displacement due to external force or change of temperature. The elasticity is the foundation of studying plasticity, fracture mechanics and finite element method. This course shows the mathematics modeling process of mechanics problems completely, and establishes the basic equation and boundary condition of the elasticity and proceeds to beg the solutions of some problems. The foundation of the elasticity basic equation lays a foundation for further number method

Introduction3, The relationship to the other courses:Theoretical mechanics: study statics and dynamics of therigid body (constraint force, velocity, acceleration)Material mechanics: research stress and displacement of thebar structure piece that is pulled, pressed, sheared, bent orturned.andStructural mechanics:researchinternalforcedisplacement of the bar structure.Plasticity: plasticity analysis and design of the structureElasticity: stress and displacement analysis of general planeproblem, plate, shell and entity structure etc.5
5 Plasticity: plasticity analysis and design of the structure. 3、The relationship to the other courses： Material mechanics: research stress and displacement of the bar structure piece that is pulled, pressed, sheared, bent or turned. Theoretical mechanics: study statics and dynamics of the rigid body (constraint force, velocity, acceleration). Structural mechanics: research internal force and displacement of the bar structure. Elasticity: stress and displacement analysis of general plane problem, plate, shell and entity structure etc
