The scientists studied how cylindrical panels made of Aluminum 7075-T6 behave when compressed. They tested different methods to find the critical buckling load, comparing experimental results with computer simulations. They found that the panel angle, length, and thickness affect the critical buckling load. The method based on applied load versus average axial strain gave the highest value, while the method based on applied load versus square of out-of-plane deflection gave the lowest. The critical buckling load increases as the panel angle increases.
