초록
Metallic sandwich plates are ultra-light materials with not only high strength and stiffness but also multifunctional. Inner dimpled shell structure can be fabricated by piecewise sectional forming process, and then bonded with same material face sheets by resistance welding. Tests have shown that sandwich plates with dimpled shell structure subject to bending have more collapse load, energy absorption and deflection before collapse than other types of sandwich plates. Consequently, inner dimpled shell structure can improve formability of sandwich plates for bending.
