This contribution presents a framework for decoupled homogenization of particle-reinforced elastomers consid­ ering interface cohesion. The homogenization scheme involves the determination of a representative micro-scale sample, numerical material tests, and identification of macro-scale material parameters. The framework is ap­ plied to isotropic micro-scale samples across a full range of interface bonding stiffnesses. Results indicate a strong dependence of sample behavior on the bonding stiffness, particularly affecting the expansive volumetric behavior.
