Periodic and homogenized bending response of faceplates of filled web-core sandwich beams

The paper presents investigation on periodic and homogenized bending response of the faceplates of filled web-core sandwich beams. The investigation is carried out using analytical, numerical and experimental methods. It is shown that the interaction between the web and faceplates and the filling material is complex phenomena. This affects the warping-induced deflection of the faceplates. The filling material stiffens the beams and reduces the shear-induced warping-deflection and resulting normal stress in the faceplates considerably. The homogenized solution is shown to agree with the periodic response well in terms of deflections. However, the normal stresses in the faceplates are considerably underestimated with the homogenized solution.
