Abstract
This thesis aims to investigate the critical local buckling of simply supported sinusoidal panels subjected to uniaxial compression using the Rayleigh-Ritz method. Being increasingly and innovatively used in many applications, these corrugated panels are especially popular due to their high stiffness to weight ratio and increased out-of-plane rigidities. Failure of such thin-walled panels occurs mainly in buckling rather than material failure. Conventional analytical methods are limited when analyzing these panels in local buckling because of its unique geometries. Hence, a semi-analytical solution is developed to predict the local buckling based on classical shell theory with a unit cell approach, and it shows excellent correlation with the results based on the numerical finite element analysis. Parametric studies are conducted to explore the effects of the thickness, aspect ratio, and corrugated amplitude of the panel on buckling. The results show that the local buckling can be accurately captured at high thickness/radius of curvature ratios, any aspect ratios, and high corrugated amplitudes. The proposed semi-analytical solution can be confidently used to aid in the efficient and accurate design analysis and optimization of corrugated panels.
