Effect of Face-Sheet Stiffness on Buckling of Curved Plates and Cylindrical Shells of Sandwich Construction in Axial Compression
Abstract
A study is made of the effect of the flexural stiffness of the face sheets on tebuckling of elastic curved plates and cylindrical shells of sandwich construction subject, to axial compression. The study shows that when the core is very weak in shear, the flexural stiffness of the face sheets can have an important effect on the buckling load. Simple formulas are developed which give good approximations to the buckling load for most practical ranges of the parameters where the effect of face-sheet stiffness is important. Results of these formulas are compared with exact results for an infinitely long curved plate over a large range of sandwich-sheel parameters. The results are based on a linear buckling theory for sandwich shells of the Donnell type.
