Elastic Disordered Microcellular Metal Rubber (EDMMR) is a lightweight metal material widely employed for damping or support in high‐temperature environments, addressing the limitations of traditional polymer rubbers. In this study, three sets of solid finite element models of EDMMR with different relative densities were developed using Virtual Manufacturing Technology (VMT). Thermal‐mechanical coupled finite element simulations explored the dynamic evolution of two typical spatial topological structures in the material’s microstructure: unit contact characteristics and angle distribution under temperature variations. Results indicate that the mechanical performance of the material under high‐temperature loads exhibits distinct spatial topological structures compared to those at room temperature. At 100°C, 200°C, and 300°C, the material experiences internal stress distributions of up to 0.5 MPa, 1.2 MPa, and 1.8 MPa, respectively, due to expansion. Additionally, during the initial loading stage, stress differentials of approximately 0.4 MPa are observed between different temperatures due to boundary effects. Furthermore, the study investigates the probability density distribution of typical microstructural combinations of EDMMR along the forming direction based on VMT, enhancing the generality of the constitutive model. Finally, three groups of EDMMR samples with different relative densities were prepared using standardized processes, and the model was validated through high‐temperature quasi‐static compression experiments.This article is protected by copyright.
