Study of Sandwich Plate System in three-point bending considering effect of adhesive

Abstract

A new method for equivalent bending modelling of Sandwich Plate System considering the effect of adhesive proposed in this paper. The steel panel and the adhesive are equivalent to a laminated plate by using laminated plate theory, and the expressions of equivalent parameters are derived. Two equivalent methods, including the sandwich theory and the proposed method in the paper, are respectively used to build the model of Sandwich Plate System under three-point bending. According to the comparison between the numerical results and the experimental results, it is assumed that the proposed method is appropriate to study bending research of Sandwich Plate System composite steel.
