Buckling Coefficients for Flat, Rectangular Sandwich Panels with Corrugated Cores under Edgewise Compression

摘要

The report presents curves of coefficients and formulas for use in calculating the buckling of flat panels of sandwich construction with corrugated cores under edgewise compressive loads. The formulas apply to sandwich panels having: (1) one facing of orthotropic material, the other facing of an isotropic material; (2) both facings of orthotropic material; or (3) both facings of isotropic material. Parameters are chosen so that facings may be of different thicknesses and so that facings can also be of different isotropic or orthotropic materials. Equations are presented for various edge conditions, simply supported and clamped. Curves of buckling coefficients are presented for simply supported sandwich panels with both facings either isotropic or orthotropic. (Author)
