【摘要】 本文对材料的应力应变关系提出了一个新的概念,认为在整个变形区间内其关系曲线是连续而光滑的。这种关系用35CrNi3MoVA,40Cr,38CrMoAl,45~#等四种钢的拉伸试验结果进行了验证,还以厚壁园筒为例,在内、外受压的条件下进行了弹塑性分析。更多还原

【Abstract】 In this paper a tensile stress-strain relationship for inelastic material behavior is formulated The curve is continuous and smooth over the whole deformation range. Experiments for 35CrNi3MoVA, 40Cr, 38CrMoAl, 45# steels have been carried out to examine it. And as an example, a thick walled cylider subjected to uniform internal and external pressure are analysed.更多还原
