基于ABAQUS的耐火材料细观损伤本构模型的开发与实现

ccording to the complex nonlinear mechanics behavior and the damage mechanisms of refractory materials, damage constitutive model of refractory materials was put forward based on the interphase model by the method of micromechanics. Utilizing the model proposed, a subroutine was developed through the commercial software ABAQUS. Using the subroutine, the damage of the magnesium carbon refractory was simulated under compression. The results of the simulation are in good agreement with the experimental data.
