Numerical Simulation Study of Concrete Cube Compression
In order to explore the mechanical properties of concrete under uniaxial compression,the compressive failure process of concrete cube was numerically simulated,the mass scaling technique and element failure criterion were introduced to improve the accuracy of the numerical simulation,and the concrete HJC model parameters were debugged.The results show that the values of the mass scaling coefficient and the maximum principal strain parameter will have a significant impact on the numerical simulation results,and under the premise of using reasonable mass scaling coefficient and unit failure parameters,the HJC model can accurately simulate the failure process of concrete cube compression,and the failure morphology and stress-strain curve are in good agreement with the test results.The research results provide a certain reference for the numerical simulation of concrete materials under complex stress conditions.
