Eigenvalue analysis of curved sandwich panels loaded in uniaxial compression
Keywords:
curved panels, sandwich panels, composite structuresAbstract
An energy formulation of a simply supported cylindrically curved sandwich panel loaded in compression is introduced and the corresponding potential energy function is evaluated. The mechanical model of a cylindrically curved sandwich panel comprises three interacting buckling modes, corresponding to nine degrees of freedom comprising qs, qx and qy components of local snake (m, n) and overall (k, l) modes, the related local hourglass (m, n) mode, Finally, closed-form solutions are presented for the global and local buckling modes.
