Cylindrical shell buckling
Webunstiffened cylindrical shells. 1. Introduction The search for high-fidelity estimates of the buckling capacity of thin shells, particularly of cylindrical and spherical thin shells, has long been a cherished goal of the mechanics’ community. Thin shells are highly sensitive to imperfections (Koiter 1945), and thus their Webof buckling of the thin axially-compressed cylindrical shell is presented, based on the addition of a length effect to the classical (Koiter circle) critical load result. Checks …

WebThe buckling behaviour of stiffened cylindrical shells has been investigated by several authors, e.g. Harding (1981), Dowling & Harding (1982), Ellinas et al. (1984), Frieze et al. (1984), Shen et al (1993), Tian et al. (1999). In the calculation of shell buckling strength the initial imperfections should be taken into account. WebNov 20, 2024 · Buckling is the most common type of failure associated with circular cylindrical shells (CCSs) subjected to axial compressive forces. This is mainly due to large radius-to-thickness ( R / t) ratio of such …
