A practitioner-led case study on buckling failure in thin-walled shell structures, using real industrial incidents to explain elastic instability, pressure differentials, and thermal effects. The notes integrate PD 5500, EN 1993-1-6, and FEA to show how buckling governs failure before material yield, with clear safety lessons applicable to design, operation, and integrity work.
