摘要

摘要本文首次在基于调和函数和势理论方法的热弹性一般解的基础上,给出了受倾斜刚性圆柱结构挤压的弹性半空间的三维热力学解析解。所得到的解被证明是封闭的。通过与文献中无热效应的接触面接触位移和接触压力的比较,充分验证了该方法的有效性。在均匀热流密度下,复合材料接触区域的温度几何分布也与前人的研究一致。此外,为了工程应用,给出了倾斜刚性圆形限流器与弹性半空间热接触问题的数值算例,详细讨论了关键场变量的分布以及热流密度对接触压力和法向位移的影响。

Three-dimensional thermal-mechanical analytical solutions for the half-space pressed by an inclined rigid cylindrical structure
Abstract Three-dimensional thermal-mechanical analytical solutions to the elastic half-space pressed by an inclined rigid cylindrical structure are presented in this article for the first time, based on the recent thermo-elastic general solutions in terms of harmonic functions and potential theory method. The obtained solutions are proved to be closed. The adequate validations are provided by comparing contact displacement and contact pressure on the contact plane from the presented solutions with those without heat effect in literatures. The geometric distribution of temperature on the contact region is also in accordance with that by previous researcher for the composite material under uniform heat flux. In addition, for the purpose of engineering application, a numerical example which is thermal contact problem between an inclined rigid circular displacement restrictor and elastic half-space is given, and the distributions of key field variables and effects of heat flux on contact pressure and normal displacement are discussed in detail.
