一、流变学的实用性流变学(Rheology)虽然是一门属于力学范畴内的基本理论学科,然而由于其对象是材料,其内容是流动和变形,所以与只研究物体运动规律的力学显然不同。研究材料流动和变形规律时,不能不联系到材料本身内部的结构和性质,只有从掌握内部结构中质点相对运动的规律时,才能区别出材料变形中所表现的弹性、粘性、塑性等不同的形态来。流动和变形,从宏观分析,都可归结为应力与应变的关系随时间发展的规律。然而
1. Rheology of Rheology Although Rheology is a basic theoretical discipline within the category of mechanics, its object is material and its content is flow and deformation. Therefore, it is related to the study of the laws of motion of objects only. Obviously different. When studying the law of material flow and deformation, we must not relate to the internal structure and properties of the material. Only by grasping the law of the relative motion of the particles in the internal structure, can we distinguish the elastic, viscous, and plasticity manifested in the material deformation. Form to. Flow and deformation, from the macroscopic analysis, all can be attributed to the law of the relationship between stress and strain over time. however
