Title: Buckling Analysis of Composite Sandwich Plates with Flexible Core Using Improved High-Order Theory.
Authors: Khalili, S. M. R.; Kheirikhah, M. M.; Malekzadeh Fard, K.
Abstract: A new improved high-order theory is presented for global and local buckling analysis of sandwich plates with soft orthotropic core. Continuity conditions for transverse shear stresses at the interfaces as well as the conditions of zero transverse shear stresses on the upper and lower surfaces of plate are satisfied. Overall buckling loads, as well as wrinkling loads, are obtained for various sandwich plates. Effect of geometrical parameters and material properties of face sheets and core are studied on the overall buckling and face wrinkling of sandwich plates.
