Abstract:

依据压入理论和弹塑性接触有限元分析,提出了采用70.3°锥形压头完成压入测试并基于能量方法获取金属材料本构关系的方法(Constitutiverelationshipbasedonenergymethodofindentation,CR-EMI)。该方法揭示锥形压入能量比与Hollomon屈服应力之间存在线性律,结合该线性律和载荷P-位移h曲线实现了材料Hollomon模型参数求取;同时,提出采用Hollomon模型参数并基于能量方法预测布氏硬度的方法(HardnessbasedonEnergyMethodofIndentation,H-EMI)。通过对多种金属材料进行压入试验和有限元分析,验证了CR-EMI方法和H-EMI方法的有效性与精确性。
