Consider investigating the free vibration of a sandwich beam using several types and geometries of honeycomb cores, including hexagonal, auxetic, and irregular configurations. What impact will these cores have on the inherent frequency of the sandwich beam? What methods may be used to ascertain if a core has a high or low natural frequency?

Hi Mukund A Patil
Since the frequency is solely determined by geometry, your investigation is essentially a geometric one.
To conduct such an investigation, use any CAD system that allows you to create the necessary lattices. The type of simulation you require is simple and can be performed in any CAD system.
Good luck!
