Abstract

This research aims to investigate the effect of imperfect length on the buckling behaviour of cylindrical shell having triangular waves. Seventeen mild steel cylinders were manufactured with a constant imperfect wavelength, 2A = 0.56.All of the samples were manufactured with 1mm mild steel plate and were cut using laser jet machine. Next, the cylindrical samples were all tested under axial compression. The collapse loads of all samples were validated by comparing the experimental results and the numerical results. In this project, all of the results show a small difference percentage of similarity, which is less than 10 percent between the experimental and numerical results. These results can be validated comparing the load versus displacement plot and the deformed shapes. From the results, it can be concluded that the collapsed load decreases as the number of waves increases.
