The creep properties of calcium silicate hydrates (CSH) are assessed by means of
nanoindentation creep experiments on a wide range of substoichiometric cement pastes …

This paper deals with micromechanical analysis of anisotropic damage and its coupling with
friction in quasi brittle materials. The anisotropic model is formulated in the framework of …

Characterizing the elastic properties of carbonate rocks is a crucial parameter in
geotechnical and reservoir engineering. However, these natural materials exhibit a wide …

With an annual per capita consumption of one cubic meter, concrete is the most
manufactured material on Earth. But concrete subject to sustained load creeps, like chewing …

A micro-mechanical constitutive model for the plastic behavior of cohesive granular
materials with hardening due to porosity changes is proposed. The plasticity model is based …

Though the solution to the limit analysis problem of the hollow sphere model—with a von
Mises matrix and under spherical symmetry—is well known, it is not available, to our …

Making use of limit analysis theory, we derive a new expression of the macroscopic yield
function for a rigid ideal-plastic von Mises matrix containing spheroidal cavities (oblate or …

The viscoelastic Poisson's ratio of concrete is an essential parameter to study creep and loss
of prestress in biaxially prestressed structures. Here we first aim to scrutinize the various …

Many geophysical studies in reservoir characterization focus on the variations in the elastic
properties of rocks. They commonly involve seismic data, which are processed in terms of …

Résumé Malgré une mise en oeuvre en apparence très simple, le béton manifeste une
grande complexité, provenant de ses caractères multiéchelle et multiphysique. Le plâtre pris …
