3D models of specimens with a scarf joint to test the adhesive and cohesive multi-axial behavior of adhesives
Autor: Claudiu Badulescu, Jean-Yves Cognard, Dominique Leguillon, Nicolas Carrère
Publikováno v: International Journal of Adhesion and Adhesives. 62:154-164
In this paper, accurate numerical analyses of the stress distributions within the adhesive in scarf joints under elastic assumption using 3D models are developed. An elastic limit model that takes into account the hydrostatic stress and von Mises equ
