Concrete Component Damage Simulation Based on Random Aggregates
In order to simulate the random distribution of concrete aggregates,this paper proposes a random aggregate placement algorithm and interference detection algorithm based on spherical aggregates.The algorithm is used to generate a three-dimensional random aggregate model of concrete,and nonlinear analysis of concrete components is conducted.The specific implementation steps of this paper include designing an algorithm for placing spherical aggregates and detecting interference,using Python to write a program to generate a three-dimensional random aggregate model of concrete,and importing the random aggregate model into ABAQUS for damage analysis.Results analysis shows that the designed random aggregate model meets the requirements of randomness,the placement algorithm is concise and applicable,and the placement ratio of aggregates of different particle sizes can be controlled.The implementation of secondary development based on Python for ABAQUS improves the efficiency of random aggregate placement and makes concrete components more versatile.The mesh partition of the random aggregate model meets the requirements of finite element analysis,providing a new method for nonlinear analysis of concrete structural components.
