摘要 在对蓝宝石进行纳米压痕试验的基础上,利用有限单元法建立了纳米压痕试验的数值模型,对蓝宝石的纳米压痕试验进行模拟、计算和分析,确定了蓝宝石表层的材料性能和力学特性。该模型可以研究在加工过程中,主要工艺参数对加工效果、加工效率、所导致的加工表面损伤层的影响,确定它们之间的相互关系,进而优化工艺参数,完善蓝宝石材料精密研磨加工的水平。 The finite element model was set up based on the nanoindentation experiment,the calculation and analysis were implemented on sapphire to gain the materials character and microcosmic engineering properties.The model was used to study the effect of craftwork parameter and the surface affected layer,make sure the correlation of it,to optimize the craftwork parameter and perfect the sapphire precision lapping.
