本文回顾了建立在物理介视力学基础上的固体范性形变与断裂的研究概况,从物理介现力学角度看,处于载荷下的固体是一个多层次的自治体系.依尺度不变原理,在微观、介观、宏观尺度上的范性流变,本质上是相互关联的.整体介观体积在介观尺度上按照“切变加旋转”的方式运动.固体范性形变与断裂可考虑为同样过程的二个阶段.
In this paper, we review the general research status of solid-scale deformation and fracture based on physical meso-mechanics. From the point of view of physical mechanics, the solid under load is a multi-level autonomous system. According to the principle of constant scale, the paradigm shift at the microscopic, mesoscopic, macroscopic scales is essentially interrelated. Mesoscopic volume in the mesoscopic scale in accordance with the “shear plus rotation” mode of movement. Solid model deformation and fracture can be considered for the same two stages of the process.
