Deformation and Strength of a Cylindrical Shell Subjected to a Concentrated Twisting Couple

抄録

In this paper, a cylindrical shell with simply supported ends subjected to a concentrated twisting couple on its middle surface is discussed. A theoretical solution is obtained from the strict consideration of the properties of singularities in the cylindrical shell under the action of two types of concentrated loads, that is, circumferential and axial ones. Numerical results are presented for shells of radius to thickness ratios of 50, 100, 150 and 200 with a length to radius ratio of 4. They show that the radial displacement and bending stresses which do not exist in the case of the two-dimensional problem of elasticity appear owing to the existence of the curvature of the cylindrical shell. And also they are not so small as we expected and become large as the ratio radius/thickness increases.
