金属塑性损伤的电阻测试法
THE RESISTANCE METHOD OF SURVEYING METAL PLASTIC DAMAGE
【摘要】 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。
【Abstract】 This paper presents a new method-the resistance method ofsurveying metal plastic damage.On the basis of test data to steel A3 usedgenerally in engineering,a mathematical model of metal plastic damageD expressed by resistivity ρis given out. This model is related togeometry.
