Buckling of WBK Cored Sandwich Panels under Longitudinal Compression

Bucking behaviors of WBK (Wire-woven Bulk Kagome) cored sandwiches under longitudinal compression are studied. Slender and short specimens are fabricated of mild steel wires and face sheets, and are fixed through copper brazing. And buckling experiments with axial compression are carried out. The failure mechanisms are analyzed by the theory and numerical simulation. Effects of eccentricity of loading or geometry, and fixings at both ends are investigated. Practical and physical meanings of the results and potential of WBK as a sandwich core are discussed.
