本文介绍了一种测量金属塑性损伤的新方法——电阻测试法。通过对工程上常用金属材料A3钢的实验测试,导出了用电阻率ρ表示的金属塑性损伤D的数学模型,此模型是几何条件相依的。
This article describes a new method for measuring plastic damage in metals - resistance testing. Through the experimental test of commonly used metal material A3 in engineering, the mathematical model of metal plasticity damage D expressed by resistivity ρ is deduced. The model is geometrically dependent.
