WebFeb 12, 2024 · The buckling behavior of a porous cylindrical shell with and without GPL reinforcement is analyzed and displayed in Table 4 for simply–simply supported (S–S) and clamped–clamped (C–C) edge boundary conditions. It is evident that adding GPLs to a porous cylindrical shell improves its buckling performance dramatically. WebThe buckling behavior of thin-walled cylindrical shells is understood for simple torsional loading, where classical elastic buckling theory uses the potential energy approach to describe the stability of the shell.2 Donnell equations, described in Refs. 3 and 4, are frequently used to determine the deformation of a cylindrical shell under lithium wireless power https://bradpatrickinc.com
