    Abstract

    This paper presents an improved model for the prediction of the adherend plastic dissipation in the peel test, thereby allowing the determination of the critical fracture eaergy. The model, which is based on earlier work, takes into account the effects of adhesive shear stresses, and a bilinear stress-strain response for the flexible adherend. Treating the flexible adherend as a beam-on-elastic foundation, expressions for the normal and shear foundation constants due to the compliance at the root of the adherend under elastic-plastic loading are derived using the deformation theory of plasticity. Application of the model to experimental peel data shows that it gives an improved estimate of the critical fracture energy.
