Damage-Based Approach for bimodular and anisotropic materials

ABSTRACT This work intends to present the development of a formulation based on Continuum Damage Mechanics to deal with elastic media introducing different mechanical behaviors in tension and compression regimes as well as some anisotropy degree when damage processes take place. First of all, a form...
