Article
Full-text available
An efficient modeling procedure is proposed for viscoelastic (VE) solids subjected to large numbers of loading cycles. While the Laplace-Carson transform (LCT) is often used to solve VE creep or relaxation problems, the originality here is an efficient extension of the approach to a plethora of cycles, based on some key ingredients. The time histor...
Article
Experimental results of cracking in heterogeneous clay samples during desiccation are reported, as well as an associated numerical model which is investigated for comparison. The clay samples embed rigid inclusions to induce heterogeneous strain fields during the drying. Crack paths and local strain fields are monitored during the desiccation proce...
Thesis
Full-text available
This thesis is focused on the modeling of crack propagation in random heterogeneous materials or induced by desiccation. A stochastic approach to the modeling of brittle fracture in random media is first proposed. Monte Carlo simulations are specifically conducted to explore microstructural configurations and to subsequently build and identify a m...

Conference Paper
Full-text available
In this work, a computational framework to simulate crack propagation in a heterogeneous material under drying conditions is proposed. The numerical approach is based on a finite strain phase field formulation, devised to reproduce experimentally determined crack paths and deformation patterns(under given boundary conditions). The effects of geomet...
Conference Paper
Full-text available
Dans ce travail, nous présenterons une approche stochastique pour caractériser la propagation de fissures dans des milieux hétérogènes à propriétés d'élasticité et d'endommagement méso-scopique. Les propriétés méso-élastiques sont obtenues via une méthode d'homogénéisation par fenêtre glissante sur des microstructures de référence. Le champ aléatoi...
Article
A stochastic approach to model crack propagation in random heterogeneous media, using mesoscopic representations of elastic and fracture properties, is presented. In order to obtain reference results, Monte-Carlo simulations are first conducted on microstructural samples in which a pre-existing crack is propagated by means of a phase-field approach...
Conference Paper
Full-text available
In this work, a method is proposed to describe cracks in random heterogeneous media. To avoid describing all heterogeneities, we propose a simplified model which takes into account local fluctuations due to both elasticity and damage parameters variability through a filter based technique.

Project
The general purpose of Labex MMCD (Modélisation et Expérimentation Multi-Échelle des Matériaux pour la Construction Durable) is to develop advanced fundamental research for the detailed understanding of the physical phenomena governing the properties of construction materials and geomaterials, from their elaboration, through their usage, to their recycling. It relies on the various scientific skills available within the Paris-Est community, including theoretical and numerical modelling from atomistic to structural scales and experimental investigation, involving in particular innovative manufacturing processes and multiscale imaging techniques of materials.
