Analysis on Rigidities and Vibration of Various Corrugated Core Sandwich Panels

Corrugated core sandwich panels are relatively lightweight structure components compared to their large flexural rigidity, and are widely used in automotive, aerospace, ship, and plant industries. However, research on rigidity and vibration for these sandwich panels remains fairly poor. In this study, the optimal sandwich panel is determined by presenting the rigidities of corrugated core sandwich panels with sinusoidal, triangular, trapezoidal, and rectangular waves. Furthermore, by analyzing the vibration of the sandwich panels for arbitrary boundary conditions, a basic visual program for practical and efficient static and dynamic design data extraction of the sandwich panels is completed.
