Stress and strain controlled cyclic loading

Abstract

In this paper introducing a nonlinear constitutive integral equation with singular kernels the authors have obtained the stress (strain) response by cyclic imposed strains (stresses). The Mullins and Payne effects are taken into account using a damping function related with the initial damage and nonlinearity using the Ogden equation by large strains. Comparisons between theory and experimental data in both cases (strain and stress controlled tests) are made.
