AbstractExperimental single lap joint tests with different interlocking structures in the interface area of carbon fiber reinforced plastic and thermoplastic parts motivates an extended simulative study about the influences of interlocking elements. Due to a lack of information from a small number of experimental test with interlocking elements, conclusions are hard to draw about how to place structures elements in multi material joint interface. A Monte-Carlo simulation approach with a large number of simulations is used to provide more general explanations of the effects and interaction within interlocking interface boundaries. The derived conclusions are a wide distribution of pins, a certain pin density, as well as a staggered positioning of pins to achieve a maximum load capacity and minimum damage initiation in the composite for small displacements.
