| 摘 要： | 对基于四棱锥Vickers压头的S45C钢仪器化压入进行了有限元数值仿真,并从载荷-位移曲线和弹性模量识别结果两个方面对S45C钢仪器化压入有限元仿真结果和仪器化压入实验结果进行了比较.结果表明,S45C钢仪器化压入有限元仿真结果与仪器化压入实验结果能够较好吻合.S45C钢弹性模量仿真识别结果和实验识别结果与标准单轴拉伸实验结果之差分别为2.28％和4.21％.

| Abstract: | Instrumented indentation on S45C steel with Vickers indenter was simulated by finite element in this paper. Comparison between finite element simulation of instrumented indentation and instrumented indentation experiments was acted from two aspects, load-depth curve and determination results of elastic modulus. The result of finite element simulation agrees well with the results of instrumented indentation experiments. The difference of elastie modulus of S45C between determined by instrumented indentation and the result of standard uniaxial tension experiment for finite element simulation and instrumented indentation experiments are 2.28% and 4.21%, respectively. |
