일방향 보강판의 최적구조설계에 관한 연구

초록

A sandwich unit in which the two facing plates are separated but rigidly connected by two simple pallel-strip arrangement panel units is investigated. A number of these units can be welded along the facing plates to form a simple parallel-strip arrangement sandwich panel. The sandwich panel is transformed into a equivalent homogeneous orthotropic plate. Formulation of bending, twisting and transverse shear stiffness of orthotropic plate is presented. The above formulas are applied to structructural optimization study of stiffened sandwich panel.
