摘要
Abstract
Numerical analysis software MATLAB has been adopted to simulate and generate random pore.Pore coordinates and aperture have been imported into ANSYS software with APDL program to make finite element analysis.Two-dimensional numerical calculation model of concrete pore mesoscopic element has been set up, element birth and death technology has been adopted to simulate the damage process of concrete pore, influence of pore distribution on mechanical behavior of concrete has been analyzed.Research results have shown that pore distribution affects the damage behavior of concrete.When the porosity of concrete is the same, the smaller aperture, the bigger strain and damage area;the ductility of concrete can be improved and the concrete will be with better cushion property.关键词
