Development of a finite element simulation methodology for the analysis of thick-walled hydrogen tanks

Kurzfassung

The aim of this thesis is to develop a methodology for the simulation of thick-walled hydrogen tanks. The developed methodology should be able to simulate the fibre architecture as well as the inter-laminar behaviour of the structure under internal and external loads. For the selection of a methodology, preliminary investigations are carried out on a simplified tank model and a final investigation on a real tank model under various load cases. The parameters for a simulation methodology were derived from the test results. The methodology models the fibre architecture in detail and can be adapted in terms of computational effort. The application of the methodology has shown that meaningful results can be achieved.
