Abstract For the nonlinear mechanical behavior of multiphase composite refractory under compression, on the basis of microscopic damage mechanics, the improved generalized self-consistent model was solved inversely, the damage behavior of multiphase refractory under compression load was investigated, and a method that can characterize the nonlinear damage behavior of multiphase refractory under compression load was proposed. Taking the AMC (aluminum-magnesium-carbon) multiphase refractory as an example, the mechanical behavior under compression was characterized by this method. The results show that the characterization results of this method are in good agreement with the experimental values, which provides an idea and a theoretical basis for the damage characterization of multiphase composite refractory.

Key words： microscopic damage mechanics multiphase refractory damage characterization generalized self-consistent model nonlinear mechanical behavior
