Abstract

Journal of Elastomers & Plastics, Ahead of Print.
Rubber-like hyperelastic materials exhibit stress softening (Mullins effect) and irreversible residual deformation (permanent set) during cyclic loading. This work proposes a simplified phenomenological two-phase softening model that simultaneously ...
