摘要

摘要: 纳米压入试验已经成为微尺度材料力学性能测试的重要方法。分析了3种代表性的弹性模量纳米压入识别方法—Olive-Pharr方法、Cheng-Cheng方法和Ma方法的有效性,并通过有限元数值模拟分析了这3种方法的测试精度和对仪器柔度标定误差的敏感性。结果表明:Ma方法适应性更强,同时具有更高的测试精度和更低的仪器柔度标定误差敏感性。

Abstract: Nanoindentation is an important method on measuring mechanical properties of materials at small scale.In this paper,the effectiveness of three representative indentation methods including olive-pharr method,Cheng-Cheng method and Ma method is studied.The accuracy and the effect of machine compliance calibration error are also investigated by means of the finite element analysis.It is concluded that Ma method is the best adaptability,the highest accuracy and the lowest sensitivity for machine compliance.The indentation results of aluminum and steel verifies the above-mentioned conclusions.
