面内に圧縮力を受ける樹脂サンドイッチ鋼板の強度に関する研究

抄録

The purpose of this paper is to investigate the compressive strength of steel-polymer-steel laminated sandwich plate, which can be influenced by the shearing behavior of the core polymer, According to analytical investigation, simplified equations are derived to estimate the buckling strength of laminated plates, of which 4 edges are simply supported, under compressive force on 2 edges. Then introducing of the newly proposed parameter on width-thickness ratio makes the estimation of the ultimate strength easy. These analytical results showed good agreement with experimental results.
