主　　题：Corrugated sandwich panel Equivalent material parameter Theoretical prediction Bending loads 

摘      要：In this paper,an aluminum corrugated sandwich panel with triangular core under bending loads was ***,the equivalent material parameters of the triangular corrugated core layer,which could be considered as an orthotropic panel,were obtained by using Castigliano s theorem and equivalent homogeneous ***,contributions of the corrugated core layer and two face panels were both considered to compute the equivalent material parameters of the whole structure through the classical lamination theory,and these equivalent material parameters were compared with finite element analysis ***,based on the Mindlin orthotropic plate theory,this study obtain the closed-form solutions of the displacement for a corrugated sandwich panel under bending loads in specified boundary conditions,and parameters study and comparison by the finite element method were executed simultaneously.
