摘要
基于C40混凝土在不同应变速率下的单轴抗压试验结果,利用ANSYS有限元分析程序中的Solid65单元建立混凝土试件的有限元计算模型,较真实的模拟混凝土在4种不同应变速率下由开裂到破坏的变化情况,通过程序计算得出混凝土试件的裂缝发展图和混凝土试件的破坏形态,探究混凝土的破坏机理,为进一步研究混凝土的动态力学性能提供设计理论依据。
Based on the single axis anti-pressure test results of C40 concrete under different strain rate,by using Solid65 unit of ANSYS finite element program, finite element calculation model of concrete specimen was establishecLThe evolution of crack patterns and failure mode of concrete were investigated.Crack development and failure modes of concrete specimen was established through the program calculates to explore the mechanism of concrete destruction.It can provide further research and design theory of concrete on mechanical properties.
