                                             Peel stresses can be a problem
                                             at ends of lap joints of all types

                  Design practices that improve adhesive bonding. (a) Gray load vectors are to be avoided as resulting strength is
                  poor. (b) Means to reduce peel stresses in lap-type joints.
