Table 4 Buckling under combined loading: characteristics of the cylinders and experimental buckling loads

From: ASTER Shell: a simple concept to significantly increase the plastic buckling strength of short cylinders subjected to combined external pressure and axial compression

Specimen h (μm) E (GPa) \(P_{exp}\) (MPa) \(P_{exp}\) (N) \(P_E\) (MPa) \(F_E\) (N) Load ratio \(\frac{F P_{E}}{F_{E} P}\)
