本文根据在MTs815.02型电液伺服岩石与砼力学试验系统上完成的砼受压应力。应变全过程试验及相应声发射检测结果,分析了砼全过程的声发射特性,利用内变量理论建立了砼受压损伤本构模型。模型中的损伤因子可由相应声发射特性的损伤能相对比确定。经比较,所建模型与实验结果吻合较好。
This paper is based on the compressive stress of the crucible that is completed on the MTs815.02 electro-hydraulic servo rock and concrete mechanical test system. The whole process of the strain test and the corresponding acoustic emission test results were analyzed. The acoustic emission characteristics of the whole process of the crucible were analyzed, and the constitutive model of the crucible compressive damage was established using the internal variable theory. The damage factor in the model can be determined by the relative energy of the corresponding acoustic emission characteristics. After comparison, the established model agrees well with the experimental results.
