Elasto-static and elasto-plastic stress analysis of adhesive bonded tubular lap joints
Composite Structures, (1992)
Abstract
The problem of an adhesive bonded lap joint between two dissimilar orthotropic
circular cylindrical laminated shells is considered. The principal
directions of orthotropy do not have to coincide with the principal directions of
curvature, and the external loads are allowed to be of non-axisymmetric type.
The adhesive layer is modelled in two ways. The first approach assumes the
adhesive layer to behave as a linear elastic material. The second, more realistic
approach takes into account the predominantly inelastic behaviour of many
polymeric adhesives, and it is shown that the non-linear behaviour affects the
adhesive stress distribution even at low levels of external loading. The
developed numerical solution procedures have been used to conduct a parametric
study, and a few general design recommendations are given.
