Orthotropic damage coupled with localized crack reclosure processing. Part I: Constitutive laws
TLDR
In this article, the authors proposed a model for cracks opening and reclosure management based on a displacement formulation, which is easy to implement in most of the finite element codes based on displacement formulation.About:

Structural analysis of a multi-span railway masonry bridge combining in situ observations, laboratory tests and damage modelling
TL;DR: In this article, a structural analysis by means of an orthotropic damage model of a multi-span masonry railway bridge built in the early years of the 20 th century is presented, which allows for the current bridge mechanical behaviour under service loads to be assessed and the ultimate load to be forecast.

Weakest link and localisation WL2: a method to conciliate probabilistic and energetic scale effects in numerical models
Alain Sellier,Alain Millard +1 more
TL;DR: The random nature of geomaterial tensile strength, combined with a softening behaviour, leads to a strong and systematic dependency of the first crack stress value on the loaded volume, which is so important that the predictive capability of efficient damage models can be occulted by the phenomenon.

Effect of Temperature on the Basic Creep of High-Performance Concretes Heated between 20 and 80°C
TL;DR: In this paper, the uniaxial compressive basic creep of high-performance concretes (HPC) in the temperature interval 20-80°C was investigated for storage structures of intermediate-level long-life nuclear wastes.
Journal ArticleDOI
3D modelling of reinforced concrete slab with yielding supports subject to impact load
TL;DR: In this paper, numerical cracking localisation, mesh discretisation, steel bar and concrete interactions and/or contact law between the hammer and concrete are used to predict how an impact load will affect a reinforced concrete slab, some of which may be impractical or expensive.
Journal ArticleDOI
The simulation of crack opening–closing and aggregate interlock behaviour in finite element concrete models
TL;DR: In this article, the authors present a crack-plane model that uses an effective contact surface derived directly from experimental data and which is described by a signed-distance function in relative-displacement space.

Analysis of crack formation and crack growth in concrete by means of fracture mechanics and finite elements
TL;DR: In this article, fracture mechanics is introduced into finite element analysis by means of a model where stresses are assumed to act across a crack as long as it is narrowly opened, which may be regarded as a way of expressing the energy adsorption in the energy balance approach.

Nonlocal damage theory
TL;DR: In this paper, the authors proposed a nonlocal damage theory, which is based on the nonlocal treatment of damage from the local treatment of elastic behavior, and the only required modification is to replace the usual local damage energy release rate with its spatial average over the representative volume of the material whose size is a characteristic of a material.

Extended finite element method for cohesive crack growth
Nicolas Moës,Ted Belytschko +1 more
TL;DR: In this article, an extended finite element method is applied to modeling growth of arbitrary cohesive cracks, which is governed by requiring the stress intensity factors at the tip of the cohesive zone to vanish.
