【Abstract】 in this paper, on the basis of the elastic-plastic theory an analysis of the risidual stress in the cylinder of steel pressure vessels which is generated when the steel plate was made into a cylinder is given. It is pointed out that the residual stress shouldn’t be ignored for design on the mid-diameter formula,and it is proposed that the inside tangential stress of cylinder for water pressure test should be limited within 0. 8[σ].更多还原
