Abstract

This research intends to examine the effect of the buckling behavior of cylindrical shell with uneven length having square waves.Eighteen mild steel cylinders were manufactured with a constant imperfect wavelength,which is 2A = 0.56mm.All of the samples were manufactured from 1mm mild steel plate.The cylindrical samples were all tested under axial compression.The collapse loads of all samples were validated by comparing the experimental results with numerical results.Results show a small percentage different between experiment and numerical result,where the percentage is less than 10 percent.In addition,comparison of load versus deflection curve and deformed shapes are in good agreement.From the results, it can be concluded that imperfection in the form of square waves results in reduction of the buckling load of the cylinder subjected to axial compression.
