Mainly due to their low weight, low cost and ease of assembly, the adhesive bonds have emerged as a promising technology. However, the lack of adequate tools of design and control remain an obstacle to the use of the adhesives. In this work a cohesiv

Crack propagation curves on flexure adhesion tests

Publikováno v: International Journal of Structural Integrity. 4:396-406

Purpose – Two different methods to obtain crack propagation curves are considered in this work. In an analytical approach, the adhesion between the plates is considered perfect. In such case, the interface stiffness is not taken into account and th

The objective of this work is to obtain an a posteriori estimate of the discretization error of a reference problem which, in our case, is a linear elasticity problem solved using the finite element method. Classically, one assumes that both the refe

The objective of this work is to develop an efficient strategy for the resolution of many configurations of a quasi-static problem with multiple contacts. Our approach is based on the multiscale LATIN method with domain decomposition. Here we propose

International audience; In this paper, we propose a multiscale strategy for crack propagation which enables one to use a refined mesh only in the crack's vicinity where it is required. Two techniques are used in synergy: a multiscale strategy based o
