Determining Stress and Effective Elastic Parameters for Spherical Contact Problems I: Static Contact
首发时间:2008-03-11
Abstract:For intrinsic incompressible medium, the spherical static contact problems are researched. The exact elastic analytical solutions are obtained. For the elastic-plastic deformation, the plastic stress and plastic deformation are obtained by the medium features and spherical radium parameters. The effective elastic-plastic constants are expressed explicitly. Furthermore, the cracked depth is formulated explicitly with the medium features and spherical radium parameters, also. Therefore, they form a complete solution for the problem under discussion. The results are compared with observed phenomenon. The evolution rate problem is discussed also. They are valuable for industry application.
