ABSTRACT
This chapter comprises all cases of external pressure uniformly distributed around the circumference. Due to the uniform stress field in the prebuckling state, the theoretical buckling behaviour may consistently and directly be derived from the differential equations. Accordingly, a great number of solutions for different cases are available for shells of constant wall thickness. For variable, that is, stepped wall thickness and for cylinders restrained by stiffening rings, the solutions have been derived numerically on the basis of the linear buckling equations.
