地点：A18-807

摘要:

The dominate methods for the analysis of elasticity problems for finite solids with corner points are overviewed versus the numerical procedures. The key features of the mechanical field in the vicinity of the corner points are characterized.

报告二题目：ANALYSIS OF THE RADIAL PER-LAYER-NONHOMOGENEITY EFFECT ON STRESS DISTRIBUTION IN A MULTILAYER ELASTIC SOLIDS

时间：4月20日(周五)  11:00-12:00

地点：A18-807

摘要:

An analytical method for solving thermoelasticity problems for multilayer nonhomogeneous solids with arbitrarily-variable material properties within each layer is presented. By taking the example of a multilayer cylinder, the problem is attempted by means of the direct integration method along with the generalized functions technique. By this means, the explicit-form solution is obtained which allows for the adequate analysis of the stresses and displacements in multilayer nonhomogeneous solids. Special attention is given to the interlayer stress distributions for the cases of discontinuous, continuous, or smooth material profiles.

报告三题目：STRESS-DISPLACEMENT RELATIONS ON THE BOUNDARY OF ELASTIC SOLIDS

时间：4月23日（周一）  10:00-11:00

地点：A18-807

摘要:

Basing on the novel direct integration method, a technique for deriving one-to-one relations between the stresses and displacements on the boundary of a deformable solid is presented. Making use of these relations allows for the unified solutions of the problems formulated in terms of stresses, displacements or with the mixed-type boundary conditions of any kind.
