Etude et modélisation de l'endommagement d'un assemblage collé bois-bois sollicité en traction

Abstract : Joints, which are essential parts of timber structures, must be designed to support expected loads during the life of the structure. The scarf joint is present in many elements, mainly in glulam structures. The behaviour before fracture of such joints is the object of this study. The cumulated damage of the joint is followed during the loading. The joint is considered as composed from wood, wood+adhesive, adhesive. A number of damage tests has been made. These tests have been purchased till fracture occurs. It is deduced from them that the adhesive part is the only one which is damaged during the loading. The corresponding damage law is identified and the model is verified with a finite elements computation
