在各种工程领域中，阐明大范围内的摩擦滑动特性是很重要的。在这项研究中，我们制定了一个各向异性摩擦模型的正交异性和旋转的滑动面的基础上弹塑性理论。该模型也可以描述初始的微观滑动和率相关摩擦响应。此外，该模型还能较好地反映各向异性摩擦滑动的基本实验结果。并将该模型与有限元法相结合，对典型的摩擦接触问题进行了分析。然后，我们证明了各向异性参数的数值结果的影响。
In various fields of engineering, it is important to clarify the frictional sliding behavior over a wide scale. In this study, we formulate an anisotropic friction model with the orthotropy and rotation of a sliding surface based on the elastoplastic theory. This model can also describe preliminary microscopic sliding and rate-dependent frictional response. Further, basic experimental results of anisotropic frictional sliding can be pertinently represented by the present model. We also employ this model with the finite element method and analyze typical frictional contact problems. We then demonstrate the effect of anisotropy parameters on the numerical results.
