The main objective of the present research is to design, realize and validate a methodology for studying ageing of bonded interfaces, based on the development of an...

Colloque avec actes et comité de lecture. Internationale.

Grade 91 steel is a suitable candidate for structural components of the secondary and the vapour of generation IV nuclear reactors. Their in-service lifetime will last...

The isothermal steady-state creep behavior of a M5® thin sheet alloy in a vacuum environment was investigated in the (α+β) temperature, low-stress (1-10MPa) range. To...

In order to study permanent strains in bituminous mixtures, the division SMIT of LCPC has developed a thermo-controlled triaxial testing device at constant confining...

In order to design reliable concrete structures, prediction of long term behaviour of concrete is important. In fact, creep deformation can cause mechanical...

Concrete is a complex heterogeneous material whose deformations include a delayed part that is affected by a number of factors such as temperature, relative humidity...

The aim of the PhD thesis is the development of two multiphase models from a common theoretical basis, applied to two very different research fields: i) the study of...

The strength of metals, and therefore their maximum operating temperature, can be improvedby oxide dispersion strengthening (ODS). Numerous research studies are...

The goal of this study is to develop a micromechanical approach, to identify and model the elementary mechanisms in connection with the microstructural heterogeneities...

The huge enhancement of the creep of plasterboard by humid environments is an old problem in the building industry, but its origin remains unknown. To understand this...

In the framework of the development of Generation IV nuclear power plants, ASME Grade 92 ferritic-martensitic steel is a candidate material for components subjected to...

This paper investigates the creep behavior of adhesively bonded concrete/fiber-reinforced polymer (FRP) joints, through experimental and modeling approaches. The first...

Le travail présenté dans cet article s’intéresse à l’influence des charges minérales sur les propriétés mécaniques de deux adhésifs époxy bi-composants utilisés pour...

Un dispositif expérimental innovant a été conçu pour étudier la durabilité de l’interface collée béton/composite soumise simultanément à une sollicitation de fluage et...

During its life-time, a bonded assembly is subjected to various ageing mechanisms which may induce synergistic effects. In the case of civil structures strengthened by...

A partnership between IFSTTAR and ULB allowed joined experimental tests on the same ordinary concrete in order to investigate the early age mechanical behaviour since...

In this experimental and numerical thesis we have studied the behavior of a granular assembly in two different situations. In the first part, a sand track is subjected...
