This paper presents an approach for the analysis of adhesive bonded joints using the commercial finite element package MSC.Nastran.

The adherends are modeled as CQUAD4 plate elements and they are considered as generally orthotropic laminates. Consequently asymmetric and unbalanced composite laminates can be included in the analysis as adherends.

The adhesive layer is modeled with CHEXA8 solid elements by two ways. The first approach assumes the adhesive layer to be modeled as linear elastic material and the second one takes into account the typical elastic-plastic behavior of many adhesives.

Constraints equations (MPC) are used to link the adherends to the adhesive. The results obtained using this approach are displacement field along the joint, peeling and shear stresses in adhesive layer.



Keywords. Adhesive bonded joint, MSC.Nastran, laminates, coupling effects, stacking sequence, non-linear
