Abstract

An analysis is given for determining G for removing a thin layer using a wedge. Corrections are described for both friction and the plastic bending of the layer. Experimental results are analysed for adhesive joints and for cutting tests on polymers and biological materials. In all of these the fracture toughness could be found. Some general observations on schemes for analysing these tests are given.
