Abstract: Plastic collapse of a partial circle cylindrical shell simply supported at each end with the longitudinal edges free is investigated for the case of uniform radial loading. The principles of Limit Analysis applicable to a plastic-rigid structure are utilized to develop upper and lower bounds for the collapse pressure parameter, P. Bounds are obtained for a wide range in shell shape parameters with the deviation between the mean of the bounds and either bound varying between 2 and 25 per cent.
