Kurzfassung
The objective of this work was the investigation of several imperfections concerning their influence on the buckling behaviour of thin-walled circular cylindrical CFRP (carbon fibre reinforce plastics) shells subjected to compression. For that purpose ten cylinders were manufactured, measured in different ways and axially loaded. Based on the information of several measurements, ten deterministic numerical models were generated and their exactness was proofed with statistical tests. In consideration of further imperfections a probabilistic analysis using Monte Carlo method was performed. That investigation came to the conclusion, that the imperfection of the load has an enormous influence on the buckling behaviour.
