| In this work, the isotropic damage is assumed and the theoretical formulations of damage-coupled material behavior are presented based on the internal variable approach. Additionally, several methods for damage measurement and specification of material damage parameters are introduced and an experiment is performed to measure damage parameters qualitatively. Finally, the constitutive and evolution equations are implemented into a commercial finite element code, Ls-Dyna, and the results are compared with the non-damage based analysis. Throughout this work, other common approaches to Continuum Damage Mechanics and their differences from the current approach are mentioned briefly. |
