一、引言光塑性模型试验结果转换到原型的条件为:1.模型材料的应力应变曲线必须与原型相似;2.模型材料与原型材料的屈服准刚必须相同;3.模型材料与原型材料在塑性状态下的泊桑比相等;4.在变形过程中,模型材料的主应变差与条纹强度的关系必须为线性,光学松弛与力学松弛的线性极限要相同,粘弹性不明显。
I. INTRODUCTION The conditions for the conversion of the results of the photoplastic model test to the prototype are as follows: 1. The stress-strain curve of the model material must be similar to the prototype; 2. The yield of the model material and the prototype material must be exactly the same; 3. The model material and the prototype material The Poisson’s ratio in the plastic state is equal; 4. During the deformation, the relationship between the main strain of the model material and the strength of the stripe must be linear, the linear limit of the optical relaxation and the mechanical relaxation should be the same, and the viscoelasticity is not obvious.
