摘要:
提出了一类混凝土细观损伤物理模型,用于解释高性能混凝土在本构层次上的细观损伤演化特征.建立了混凝土单轴受拉、单轴受压与双轴拉压组合条件下的随机损伤本构关系模型.利用混凝土单轴受拉破坏全过程的声发射实验数据,引入随机建模理论,确立了细观损伤单元的极限破坏应变随机场分布参数.通过与一批高性能混凝土本构关系试验数据相比较,初步证实了采用随机损伤本构关系反映混凝土受力破坏机理的可行性.
Abstract:
A class of mesoscopic damage mechanics models of concrete is put forward to understand the mesoscopic damage evolution characteristics of the high performance concrete at the level of constitutional law. The stochastic damage constitutional law models of concrete under uniaxial tension, uniaxial compression and biaxial tension-compression combination are established. The acoustic emission experiments of concrete under uniaxial tension loading in whole process are conducted and the stochastic modeling theory is introduced to determine the random field distribution parameters of the limit fracture strain of the mesoscopic damage elements. The comparisons between the theoretical results and a passel of experiment results preliminarily verify the feasibility of understanding the failure mechanism of concrete through the stochastic damage constitutional law.
