Buckling experiments with composite cylinders under combined loads

What is it about?

Cylindrical shells made from composite materials are increasingly used as load carrying structures in the aerospace industry. Making precise predictions for how much they can carry when different load types occur at the same time is challenging, because only very few test data exist. In this study, a large number of experiments are done with a number of different load combinations and the results are thoroughly documented and analyzed.

Why is it important?

This paper contains the first series of experiments done with composite cylinders that considers combination of axial compression and bending load, axial compression and torsion load, as well as tests with all three load types together.
