The present paper describes the implementation of two state-of-the art non-linear finite element models for predicting the pull-out strength. The two models include a 3D-continuum model where the core was modelled using 8-node brick elements with a homogenized material model and a detailed meso scale model with accurate honeycomb cell representation using 4-node shell elements. The simulation results are benchmarked against experimental data of the reference configuration. Both models enable to predict the strength accurately, while the 3D-continuum model can be considered favourable for most applications due to the reduced computational effort.||URI:||http://hdl.handle.net/11420/2742||ISSN:||0263-8223||Institute:||Produktentwicklung und Konstruktionstechnik M-17||Type:||Sonstiges||Funded by:||German Federal Ministry for Economic Affairs and Energy , Germany, in the framework of LuFo V-2 as part of the research project ‘SYLVIA’.|
