Damage localization and rupture with gradient damage models
We propose a method of construction of non homogeneous solutions to the problem of traction ofa bar made of an elastic-damaging material whose softening behavior is regularized by a gradient damage model.We show that, for sufficiently long bars, localization arises on sets whose length is proportional to the materialinternal length and with a profile ...

FE Modeling of Circular, Elliptic, and Triangular Isolated Slabs With a Continuous Damage Model
The non-linear behavior of reinforced concrete circular, elliptic, and triangular isolated slabs was studied using computational mechanics. Concrete was modeled with a damage model which includes softening, while the behavior of the reinforcing steel was

Using a finite-element scheme based on a damage model, a numerical system is developed to predict cracks in reinforced concrete beams due to corrosion expansion. The numerical results show that the width of such cracks is affected considerably by (i) the
