本文讨论了粘弹塑性材料的力学——光学性能以及应力松弛曲线的测定方法。并在对模型材料初步探索的基础上,模拟了挤压和挤出成型过程,记录了制品模型内的应力条纹图。
This article discusses the mechano-optical properties of visco-elastic plastic materials and the determination of stress relaxation curves. Based on the preliminary exploration of the model materials, the extrusion and extrusion processes were simulated, and the stress fringes in the product model were recorded.
