薄壁圆板有限元模拟破坏前的应力-应变关系 摘要：揭示了有限元模型中低碳钢的真实应力-应变关系。从一系列长宽比不同的构件的拉伸试验中得出了这些应力-应变关系。不同于工程应力-应变关系，真实的应力-应变关系与构件的几何特性是无关的。光学测量的使用将真实应力和应变与有限单元长度联系起来，

Strain and Stress Relation Unt Fracture for Finite Element Simulations of a Thin Circular Plate Abstract：This paper presents a true strain and stress relation for mild steel that is suitable for the implementation in finite element models. This true strain and stress relation is obtained from a series of tensile experiments with specimens of different length-per-breadth ratios.
