Abstract


This study explores the behavior of corrugated sandwich plates and how it affects their mechanical and structural properties under various loading conditions. The shape and dimensions of the plate play a significant role in determining the plate's stiffness, bending moments, and deflections. Specifically, this study focuses on the impact of varying geometric parameters on the plate's properties under transverse static load, without a temperature gradient. The aim is to establish the relationship between the mechanical and structural properties, the plate's shape factors, and dimensional parameters. To achieve this, an equivalent plate model of homogenization, based on structural smearing and classical laminate theory, is used. The finite series technique is also implemented to determine the in-plane extensional shear stiffness, bending stiffness, bending moments, and deflections under transverse loads and boundary conditions for sandwich plates with corrugated cores of various configurations. The study then compares the results from the varying parameters to establish the most effective configuration for the sandwich plate construction. The study concludes that triangular configurations are the most effective.
