Hybrid Metal-Composite Interfaces: Aspects of Design, Characterisation, and Simulation

Abstract

This contribution gives an overview of the simulative engineering of metal-composite interfaces. To this end, several design aspects on the microscale and macroscale are explained and methods to model the mechanical behaviour of the interface within finite element simulations are discussed. This comprises the utilization of cohesive elements with a continuum description of the interface. Likewise, traction-separation based cohesive elements, i.e. a zero-thickness idealization of the interface, are explained and applied to a demonstration example. Within these finite element simulations, the constitutive behaviour of the connected components has to be described by suitable material models. Therefore, inelastic material models are formulated based on rheological models.
