摘要
阐述纳米压痕技术的定义和基本原理,分析了其与普通压痕实验的区别,利用先进的纳米压痕仪对脆性材料进行了球形纳米压痕实验;同时采用有限元软件Marc建立球形压痕实验三维模型,进行压痕仿真研究,实验结果与仿真基本一致。
This paper expounded the definition of nanoindentation technique and basic principle, analysed distinction be-tween its and ordinary indentation experiment. Then used advanced nanoindentation instrument for spherical nano inden-tation experiment on brittle materials; at the same time, establishing the finite element model for spherical nano indenta-tion experiment, and performed indentation simulation, experiment and simulation results were basically the same.
