Biography
Ph. D. thesis: Constitutive Behaviour and Fracture of Adhesive Layers. Chalmers Tekniska Högskola, Göteborg, Sweden, 2004 In the thesis, experimental methods are developed to determine the complete stress-deformation relation for an adhesive layer loaded in shear. Generally, the stress distribution is non-uniform in the test geometries used. Evaluation of experiments is performed using an inverse method. The idea is to measure the energy release rate as a function of the crack tip deformation. The stress-deformation relation is obtained by a subsequent differentiation. The method is shown to be capable of capturing the complete stress-deformation relation under stable loading conditions.
