FREE AND CONSTRAINED VIBRATIONAL ANALYSIS OF SANDWICH STRUCTURE BY THEORITICAL APPROACH

Abstract

Theoretically, this research investigates the free and forced vibrations of simply supported, cavity-filled reinforced sandwich structures in vacuum and water. First, it is advised to use a multi-level homogenization model to change the core layer of the sandwich structure into an orthotropic substance. Following is the first-order shear. Deformation theory (FSDT) is utilised to establish displacement fields, and Hamilton's principle is used to derive Hamilton's principle equations describing the motion of the sandwich structure.
