摘要
依据试验测得的应变数据和塑性各向异性理论,本文分析了圆板液压胀形件顶点的两个主应力的特征。从几种金属板料分析结果表明,这两个主应力是不相等的,其差值小于4%。
Based on the experimental data and the plastic anisotropic theory, this paper examines the question of whether or not the two principal stresses at the pole of a circular bulging specimen of sheet metal are equal. The analysed results for several kinds of sheet metal show that they are unequal, but the disparity between them is mostly not greater than 4%.
