ABSTRACT: Theoretical solutions are presented to clarify the effect of imperfections in the shape of the buckling mode on the buckling of clamped circular cylindrical shells subjected to torsion. The problem is solved by applying the Galerkin procedure to the Donnell basic equations governing the finite deformation of imperfect cylindrical shells. Practically accurate solutions for a wide range of shell geometries are used to assess the range of validity of an asymptotic estimate of the imperfection sensitivity based on the initial postbuckling theory of Koiter and Budiansky.
