THE LOCAL METAL HYBRIDISATION: EXPLOITATION OF THE WEIGHT SAVING POTENTIAL

Abstract

Modern lightweight materials, such as fibre reinforced plastics (FRP), show a relatively low bearing strength. Therefore, a ramp-up of the base laminate is often required which leads to an eccentricity. The local metal hybridization follows a different approach as FRP layers are substituted locally in the load intro-duction region with metal layers. Special attention has to be paid to the so called Transition Zone, where the metal layers are ending. The presented work contains investigations on the failure behaviour in static bearing tests accompanied by digital image correlation and in a nonlinear Finite Element simulation. The aim is to decrease the required metal content.
