确定球面接触时的应力和有效弹性参数i:静态接触 收藏此文 全部作者： 肖建华 第一作者单位： 河南理工大学 论文摘要： 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. 关键词： cracking depth, effective constant, plastic stress, elastic stress, incompressible medium, contact mechanics, rational mechanics 发表日期： 2008年03月11日 同行评议： （暂时没有） 综合评价：
