Comportement thermomécanique d'un béton ordinaire en compression cyclée : expérience et modélisation

Abstract

Infrared thermography observations permit to show thermal phenomena occurring on a plain concrete during a compressive test. A modelling of the thermomechanical behaviour of this materials is proposed as an extension of M. Frémond and B. Nedjar's model. It permits an interesting dialog between the experimental results and those obtained by a numerical simulation of a simple compressive test.
