Kurzfassung

The design process of lightweight CFRP structures is associated with many uncertainties. In order to counteract this and to allow structural evaluation, a comprehensive and statistically based collection of allowables is advantageous. Such physical allowables are usually determined by a number of complex and expensive test campaigns. Above all, the various possibilities of choosing materials and layups result in a large number of necessary experiments. With the help of simulations -based virtual allowables, real experiments can be complemented and the effort of the test campaigns can be greatly reduced. An important aspect of realistic simulation of virtual allowables is the correct prediction of progressive failure. However, such prediction is associated with various problems due to basic assumptions in classical continuum mechanics. The Peridynamic theory is one possibility to overcome these limitations. Peridynamics is able to inherently map progressive failure, since integral formulations are solved instead of differential formulations. In order to use Peridynamics as a scalable basis for determining virtual allowables, a number of methods and processes must be developed. Among other things, the further development of an energy-based failure of criterion within the correspondence formulation or the integration of various test models and materials must be emphasized. Finally, all of these developments are embedded in a framework and made usable. Both the actual simulation as well as pre- and postprocessing via programming interfaces (API) and graphic surfaces are made accessible and automated. In the presentation the development of such framework and its use for the prediction of virtual allowables will be shown.
