Hence, validation and verification of numerical models for these scenarios is challenging. In order to support the validation of FE models and possibly enable the development of new design approaches, the thoroughly documented results of a large number of buckling tests with CFRP shells in multiaxial loading are provided herein. The extensive experimental campaigns on the buckling of cylindrical CFRP shells in multiaxial load cases were conducted on a set of nominally identical specimens. These shells were manufactured at the Institute of Composite Structures and Adaptive Systems of DLR in Braunschweig and have been tested in a previous campaign in pure axial compression. In this study, various combined load cases comprised of axial compression and bending, axial compression and torsion, as well as combinations of all three buckling inducing load types were investigated. This publication contains a separate sheet for each considered shell, listing for all individual tests the achieved buckling loads and the loading imperfections determined from measurement data as well as the mean values and standard deviation of these data for each test point.enhttps://creativecommons.org/licenses/by/4.0/Thin-walled ShellComposite ShellBucklingExperimentCombined LoadingTechnology::620: Engineering::620.1: Engineering Mechanics and Materials ScienceExperimental Datahttps://doi.org/10.15480/882.1425810.15480/882.14258Panek, StefanStefanPanek10.2514/6.2025-233510.2514/6.2025-2335
