dyna-true total strain to effective plastic strain 在材料力学和固体力学中,应变是用来描述物体在外部载荷作用下形状或尺寸发生变化的物理量。当我们谈到“dyna-true total strain”和“effective plastic strain”时,我们实际上是在讨论两种不同的应变度量方式,这些概念通常在有限元分析(FEA)和其他计算力学方法中...
摘要: The article deals with a possibility of structure of approximate true stress-true strain diagram using the engineering stress-strain curve and mechanical properties of material. A possibility to define the curve more precisely behaind the point of instability is demonstraited....
