Peri Dynamics Simulation of Concrete Under Compression Based on Meso-Scale Model
In order to conduct numerical simulation of concrete compression,an attempt is made to gener-ate aggregate parameters based on Monte Carlo method,and then construct a bond based peridynamics nu-merical simulation method in consideration of three-phase mesostructure of aggregate,interface transition zone and cement paste.The results of numerical simulation show that the numerical simulation method combining bond based peridynamics method and meso scale model can describe the specific morphology and mechanical characteristics of concrete under compression,and preliminarily prove the effectiveness of the combination.It also shows the advantage of peridynamics method in analyzing discontinuous mechanical problems such as crack propagation and failure.
