Cecchi and Sab homogenization method (Cecchi and Sab in Int. J. Solids Struct. 44(18-19):6055-6079, 2007) for the derivation of the effective Reissner-Mindlin shear moduli of a periodic plate is applied to sandwich panels including chevron pattern. Comparison with existing bounds (Lebee and Sab in Int. J. Solids Struct., 2010) and full 3D finite element computation validates the method. Finally, the skins effect on transverse shear stiffness is put forward.
