Abstract

Sandwich panels with Corrugated cores have wide applications and play an important role in industries like vehicle, aerospace and marine industry. Corrugated-cores in the middle of the sandwich structures make them stronger under bending loads. Due to their high efficiency with low weight, considerable researchers studied the behavior of sandwich panels and most of them used numerical methods. In the other word, there is a few studies presents an Analytical solution for corrugated sandwich panels. As first time in this paper, sandwich panels with Corrugated core is investigated by using an Analytical solution based on power-series method. By using this method, one can overcome restrictions of other methods which limit the Analytical solution to special boundary conditions. First, by using double Maclaurin series, partial differential equations is extended based on first order shear deformation theory. Then, the obtained equations are solved by considering various types of boundary conditions. It is assumed that panel rested on elastic foundation and Winkler elastic foundation is used to model it. The obtained results are validated by available researches. Moreover, detailed parametric study is conducted involving geometrical parameters like core and face thickness, angle and pitch of Corrugated core, type of boundary condition and stiffness of elastic foundation.
