چکیده انگلیسی


• The buckling behaviors of sandwich panels with wire-woven metal cores are presented.
• For both types, the peak loads were governed by macroplastic buckling.
• Low shear modulus and strengths of the core substantially influenced the buckling.
• A small initial deflection greatly decreased the buckling resistance of the sandwich panels.

This article presents the buckling behaviors of two types of WBK (Wire-woven Bulk Kagome) cored sandwich panels subjected to in-plane compression. Classical theories are introduced, and the experimental and numerical results are presented. The effects of several design parameters are analyzed. For both types, the peak loads were governed by macroplastic buckling. Low shear modulus and strength of the WBK core substantially influenced the buckling behaviors of the sandwich panels before and after their peaks. A small initial deflection greatly decreased the resistance against buckling of the sandwich panels with thinner cores, as confirmed by a two-stage FEA (Finite Element Analysis) and the analytic solution accounting for eccentricity.
