Stress and strain analysis in metallic tensile specimen with different notch root radius 金属材料不同缺口根半径拉伸试样中的应力应变分析
It was found that metallic wall and fold-in appear only when thick sheet is processed with small radius tool. And after their appearance, their intensity increases as the wall angle, step size and yield stress increases. 结果发现挤出飞边和向内褶皱在使用小工具头加工厚板的时候容易出现,其程度随成形角、加工步长和屈服应力的增长而增大。
In this paper, bending and post-buckling of a graded metallic foam circular plate with density gradient along thickness and radius are investigated. 本文研究了梯度泡沫金属圆板在两种典型密度分布方式(沿厚度方向和沿径向分布)下的弯曲和过屈曲问题。
