Popis:	The focus of this work is capturing the generation of instabilities in bondlines of uncured adhesives using the finite element method. Two geometries have been studied, a cylindrical probe and a specimen representative of a possible adhesive line used in the automotive production. Such geometries have been analyzed under tensile loading considering different width/thickness aspect ratios. A Neo-Hookian material model was chosen to describe the behavior of the material and the formation of instabilities during the process. A discretization and a parametric study have been performed to show the validity of the model and the results have been found to agree with results found in literature.
