摘要

该研究介绍了一种数值方法，用于解决轴对称刚性光滑体压入不可压缩弹性层的问题。本研究提出了一种在 COMSOL Multiphysics 软件中使用变形网格界面的计算方法，通过求解网格位移的 PDE，允许离散化的内部节点在给定的斜率边界条件下移动。所提出的方法被应用于球形和锥形光滑轴对称压头的压痕问题。结果与分析解十分吻合，并且该方法显示出快速收敛性。

The computational method with the deformed mesh interfaces for an incompressible layer indentation by rigid indenters with arbitrary axisymmetric smooth profiles

The research introduces a numerical method for solving the problem of an axisymmetric rigid smooth body indenting an incompressible elastic layer. This study proposes a computational approach with the deformed mesh interface in the COMSOL Multiphysics software, which allows the discretized interior nodes to move by solving PDEs for the mesh displacements with the given slope boundary condition. The proposed method is applied to the indentation problems with spherical and conical smooth axisymmetric indenters. The results are in a good agreement with the analytical solutions, and the method shows rapid convergence.
