结构弹塑性应力分析的弹性试验模型

材料的塑性表现是弹性表现的延续和发展，二者在物理与力学性质上既有密切的联系，又各有不同．以弹塑性力学的模型理论和塑性力学形变理论的相似方程为基础，根据塑性模型理论以及原型材料的广义应力σi与广义应变εi曲线的关系，提出了以弹性解为原始数据，将其转换为不同塑性变形程度的弹塑性应力分析的弹性试验模型，并讨论了弹性与塑性应力转换的计算方法．

Resilience Test Model of Structural Elastoplastic Stress Analysis

The plastic behaviour of materials is the extension and expansion of their elastic behavlout. The two both are closely connected and distinct from one another in physical and mechanical properties. Based on the similar equations of the elastic-plastic model theory and the plastic deformation theory, this paper presents, according to the plastic model theory and the relations between generalized stress σi and strain εi curves of prototype materials, the resilience test model of elastoplastic stress analysis with the elastic solution as raw data to be converted to different plastic deformation extents, and discusses the numerical method of transformation from elastic stress into plastic one.
