摘要： In this paper, the adhesively bonded corrugated core sandwich panel is introduced and its elastic properties are discussed. Due to the relative displacement and rotation between face and core plates in adhesive joints caused by adhesive layer distortion, traditional elastic constants with considering both face and core plates to be fastened to each other are no longer fit for adhesively bonded sandwich panels. Therefore, its elastic constants with effect of adhesive layer distortion have been derived and presented in this paper. By submitting these elastic constants into closed-form solution, the response of simply supported sandwich panel under uniform load with small deflection is calculated which agrees well with 3D FEM analysis. Lastly, with the elastic constants, the effects of adhesive layer thickness and its elastic modules on both transverse shear stiffnesses with different shapes and dimensions are further studied and discussed.
