Abstract

L’objectif principal de cet article est la mise au point d’une méthodologie numérique deprévision du comportement local d’un procédé de renforcement des poteaux en bois par lafibre de carbone. En particulier, on s’intéresse à l’étude du comportementélasto-plastique du matériau bois avec effet du renforcement. Une modélisation basée surla thermodynamique des processus irréversibles avec variables d’état est utilisée pourtraduire le couplage entre le comportement plastique à écrouissage isotrope et l’effet durenforcement. Les aspects théoriques et numériques de cette formulation sont décrits endétail. La résolution du problème d’équilibre global est assurée par un schéma DynamiqueExplicite. La validation de la procédure de calcul implémentée dans ABAQUS/Explicit estfaite sur la simulation d’un essai de compression des éprouvettes circulaires en boisrenforcées par la fibre de carbone. Les résultats des simulations sont confrontés à ceuxde l’expérience.
