Resumen: The Rice Cherepanov J is calculated for a lap joint in pure shear. By setting J=Jc the critical value of J integral the fracture load of the joint is calculated for perfectly plastic behavior of the adhesive. The fracture load as function of over-lap length is evaluated both theoretically and experimentally. Three failure modes are given for the joint failure: for small over-lap length, joints fail by adhesive plastification, for middle one, joints fail by cracking and plastification in adhesive, for large one, joints fail by cracking in adhesive.
