Results are presented of an experimental investigation of unstiffened, thin-walled cylindrical shells subjected to a transverse load applied by a cushioned saddle. The cylinders were supported at the ends and the saddle load applied at midspan. Prebuckling stresses, buckling mode, and buckling load were investigated. All of the test cylinders failed in a mode that is characteristic of unstiffened cylindrical shell failure under local circumferential stresses. The only independent variable investigated in the test series was the stiffness of the saddle liner material. The liner stiffness was found to have a strong influence on the magnitude of the buckling load, with stiffer liners resulting in higher buckling loads. Author
