Mode II cohesive law extrapolation procedure of composite bonded joints

A novel extrapolation procedure to predict the mode II cohesive laws of adhesive joints is presented. At first, a recently proposed compliance based experimental method to extract mode II Cohesive Laws is extended to the eccentric end-notched flexure test EENF and generalized including the effect of...
