Abstract
In automotive engineering, epoxy as well as polyurethane adhesive bonds have to be modeled in structural simulations. Current German research projects concerning adhesive joints undertake enormous test efforts to describe their mechanical behaviour - resulting from complex testing procedures and a large quantity of recommended testing series. Additionally, a significant scatter in characteristics, especially from fracture mechanics, becomes evident. In most of these current studies, one single epoxy adhesive is studied. On this basis similar, often identical failure behaviour is used for a wide variety of epoxy adhesives in industry, as characterizations of other adhesive joints are not affordable. Complementing approaches are examined to reduce the testing effort to provide applicable methods for industrial usage for a big variety of adhesive bonds. First, simplified specimen geometries and testing setups are examined. Secondly, through investigating the influence of varying strain rate on material parameters, findings for a variety of adhesives are aimed at. Thirdly, justified by big scatter an engineering approach for the choice of material Parameters is discussed for the conservative design of products.
