What is Delamination Effects on Sandwich Beam Vibration about?

This document summarizes an analytical formulation for modeling the free vibration of sandwich beams with delaminations between layers. The formulation divides the beam into segments at delamination locations and models each segment as an Euler beam. Boundary and continuity conditions are applied to determine natural frequencies and mode shapes. Finite element analysis was also conducted using ANSYS for comparison. It was observed that delaminations reduce natural frequency and change mode shape. Strain plo
