Numerical Buckling Analysis of a Z-Stiffened Panel Model with the Experimental Method Fokker (Emf) and BOSOR4 Computer Programs

摘要

Results are reported for two numerical buckling analyses to correlate the BOSOR4 R = infinity option, for flat panel buckling, with a manufacturer-developed collapse load code, for a Z-type stringer-skin model. Good correlation was found for general instability. Results are given for elastic buckling load reduction, due to local buckling effects as computed using the manufacturer's procedures.
