摘要

采用有限元法研究了在钨试样纳米压痕试验中使用Berkovich压头和锥形压头的区别。该研究旨在确定试样的弹性模量，以及不同压头的弹性模量如何变化。有限元分析还表明，弹性模量对试样和压头的尺寸都很敏感，对其进行了多次不同尺寸的数值计算。

Comparison of finite element simulation of tungsten nanoindentation with Berkovich and conical indenter

: Finite Element Method (FEM) was used to study the difference between using Berkovich and conical indenters in nanoindentation test of tungsten specimen. The study was aimed to determine the modulus of elasticity of a tested specimen and how it changes with different indenter. The FEM analysis also revealed that the modulus of elasticity was sensitive to the dimensions of both specimen and the indenter for which were made several numerical calculations with different dimensions.
