굽힘 하중을 받는 딤플형 금속 샌드위치판재의 최적설계
Optimal Design of Metallic Sandwich Plates with Inner Dimpled Shell Subjected to 3-Point Bending
초록
Metallic sandwich plates with Inner dimpled shell subjected to 3-point bending have been analyzed and then optimized for minimum weight. Inner dimpled shells can be easily fabricated by press or roll with high quality precision and bonded with same material skin sheets by resistance welding or adhesive bonding process. Optimized shape of inner dimple is a hemispherical shell to minimize weight without failure, including face yielding, face buckling and inner dimple buckling. It is demonstrated that bending stiffness of sandwich plate is 2 or 3 times than solid plates with same strength
