Finite Elements and Localized Failure
Abstract
This project was comprised of research on three different levels: 1) Experimental Work: Stroke controlled post-peak experiments on plain concrete specimens which were subjected to direct tension, triaxial compression and direct shear; 2) Constitutive Work: Homogenization of localized failure cure to tensile cracking and frictional slip in the form of the Composite Fracture Model which describes the degradation of strength within an elementary volume of a fracture energy equivalent continuum; and 3) Computational Work: Stabilization of strain-softening computations of localized failure within solids subjected to tensile cracking and/or shear faulting. Keywords: strain softening; concrete components; fragility; anisotropy; experimental data.
