Description:The results of a parametric study of the effects of initial imperfections on the buckling and postbuckling response of three unstiffened thinwalled compression-loaded graphite-epoxy cylindrical shells with different orthotropic and quasi-isotropic shell-wall laminates are presented. The imperfections considered include initial geometric shell-wall midsurface imperfections, shell-wall thickness variations, local shell-wall ply-gaps associated with the fabrication process, shell-end geometric imperfections, nonuniform applied end loads, and variations in the boundary conditions including the effects of elastic boundary conditions. A high-fidelity nonlinear shell analysis procedure that accurately accounts for the effects of these imperfections on the nonlinear responses and buckling loads of the shells is described. The analysis procedure includes a nonlinear static analysis that predicts stable response characteristics of the shells and a nonlinear transient analysis that predicts unstable response characteristics.Hilburger, Mark W. and Starnes, James H., Jr.Langley Research CenterSHELLS (STRUCTURAL FORMS); COMPRESSION LOADS; PARAMETERIZATION; CYLINDRICAL SHELLS; COMPOSITE STRUCTURES; FABRICATION; BUCKLING; NONLINEARITY; BOUNDARY CONDITIONS; ISOTROPY; DEFECTS; FINITE ELEMENT METHOD; GRAPHITE-EPOXY COMPOSITES; ELASTIC PROPERTIESWe have made it easy for you to find a PDF Ebooks without any digging.
