In this study, the indentation hardness test is performed by elastic-plastic finite element (FE) analysis. In order to investigate the effect of the wear of indenter tip on the load-penetration depth curve (p − h curve), indentation simulation is made by changing the indenter tip radius. The p − h curve obtained by finite element method (FEM) is in good agreement with the experimental results. The calculation shows that the indentation plastic work W p corresponding to the area in the p − h curve is hardly affected by the indenter tip radius.

通过有限元分析压头尖端半径对压痕硬度的影响
在这项研究中,压痕硬度测试是通过弹塑性有限元 (FE) 分析进行的。为了研究压头尖端磨损对载荷-穿透深度曲线的影响(p - H 曲线),通过改变压头尖端半径进行压痕模拟。这p - H 有限元法(FEM)得到的曲线与实验结果吻合较好。计算表明压痕塑性功W p 对应区域内p - H 曲线几乎不受压头尖端半径的影响。
