A constitutive model for stress-strain response and mullins effect in filled elastomers

In this work we propose a new constitutive theory to estimate the stress–strain response and the softening induced by the Mullins effect during the stretching of filled elastomers. In this study, we used the Mullins and Tobin concept where the filled elastomers are treated as composites with hard‐domains and soft‐domains and the softening is due to the hard domain transformation into soft domain during stretching. Gent strain energy is assumed...
