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.　Herein,　three　sets　of　solid　finite　element　models　of　EDMMR　with　different　relative　densities　are　developed　using　virtual　manufacturing　technology　(VMT).　Thermal–mechanical　coupled　finite　element　simulations　explore　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,　200,　and　300　°C,　the　material　experiences　internal　stress　distributions　of　up　to　0.5,　1.2,　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　are　prepared　using　standardized　processes,　and　the　model　is　validated　through　high-temperature　quasistatic　compression　experiments.　©　2023　Wiley-VCH　GmbH.
