Abstract

In this work, an experimental study of low cycling fatigue in reinforced concrete elements with dominant flexural behavior is developed. The reinforced concrete elements are subjected to cycles of displacement until rupture. A total of two bending beams were tested. In each cycle, [...]

Abstract

Understanding the failure of brittle heterogeneous materials is essential in many applications. Heterogeneities in material properties are frequently modeled through random fields, which [...]

Abstract

To study the wheel/rail rolling contact fatigue of high-speed trains, we obtain the distribution of contact forces between wheel and rail by introducing the strain-rate effect. Based on the finite element simulation, a two-dimensional finite element model is established, and the process [...]

Abstract

We consider a monolithic phase-field description for fractures in nearly incompressible materials, i.e., carbon black filled ethylene propylene diene monomer rubber (EPDM). A quasi-static phasefield fracture problem is formulated in mixed form based on three different energy functionals [...]

Abstract

Global local analysis is a part of the structural analysis that allows to study, with an iterative solution, a coarse global linear model with a specific zone. This zone is defined as a local model with fine mesh and a non-linear behaviour such as crack propagation. However, the current [...]

Abstract

During its life expectancy, a RC structure is exposed to corrosion. This phenomenon attacks the reinforcement and lead to the creation of a third material that is rust, at the expense of steel. This corrosion material takes more volume than the lost volume of steel and generates internal stresses [...]
