material curve meaning in English

物质曲线

The elastic solution for elastic - plastic problem is based on model theory of elastic - plasticity and deformation theory of plasticity . with the original data which embodies the stress state of complicated structure at elastic phase and is attained by experiment or calculation , according to the similarity theory between elasticity and plasticity and generalized stress - strain material curves , and using new means and new techniques , this method and change the elastic value into plastic value correspondingly
结构弹塑性分析的弹性解法是以弹塑性力学的模型理论和塑性力学形变理论为基础的，具体做法是利用实际工程中由实验或者计算等方法获得表征复杂结构弹性阶段应力状态的原始数据，根据弹性力学和塑性力学方程的相似关系和被实验材料的广义应力应变曲线，采用新的分析方法和实验手段，将弹性解转换成对应的弹塑性解。
