| 摘 要： | 以两平行圆柱体的接触问题为实例,将“软性系数”的概念引入接触问题,利用软性系数对接触物体的力学状态进行了分析,从理论上证明了工程实际接触问题中塑性变形和塑性破坏的客观存在,从而进一步完善和发展了弹性接触理论。 |
| 关 键 词： | 静载荷 接触问题 材料 力学状态 塑性 软性系数 |

| Abstract: | Taking the contact problem of two parallel cylinders as an living example,the concept of "soft-property coefficient" is being introduced into the contact problem.Analysis on the stress-state of contacting object has been carried out by the use of soft-property coefficient.The objective existence of plastic deformation and plastic destruction in contact issues of engineering practice was testified in the light of theory,thus the theory of elastic contact is being further perfected and developed. |
| Keywords: | Cylinder Contact Stress-state Plasticity |
