EXAMPLES ARE GIVEN TO ILLUSTRATE THE UNIQUENESS LAW OF SOLUTIONS FOR PLANE PROBLEMS OF ELASTICITY

The uniqueness law of solution is the theoretical basis of the inverse method or the semi- inverse method for solving elasticity problems. The stress function method, the stress method and the stress sum function method are used for solving plane problems of elasticity to let students understand the true meaning of the uniqueness law of solution, and to enrich the solution methods and enlarge the application scope of elasticity.
