DAMAGE TO ADHESIVE SINGLE LAP JOINT MADE OF MATERIALS WITH DIFFERENT PROPERTIES UNDER STATIC LOADING CONDITIONS
Abstract eng: Adhesive joints are increasingly used in construction of machines. Calculation models for determination of strains in adhesive joints used by engineers are burdened with simplification errors. Tests of joints of homogenous materials, especially metals have already been widely discussed in literature. The goal of this study is to define actual strength of a single lap joint made of homogenous and non-homogenous materials. The tests results have confirmed that a decrease in Young modulus of bonded materials is accompanied by reduction of the joint temporary strength. It was observed that the amount of work needed for a specimen to be destroyed is similar for joints characterized by cohesion fracture through the glue layer. For specimens with adhesive or cohesive fracture running through the bonded material, the work assumes lower values.
