Project Description
This project involves the analysis of a zero-waste vibration-dampening board created from old clothes and hospital-used gloves. The board is designed to reduce vibrations and impact forces, primarily used in applications where vibration damping is critical, such as in machinery or structural components.

The board consists of three layers:

Outer Layers: Made from old clothes (fabric), providing flexibility and damping.
Core Layer: Composed of used hospital gloves (rubber), offering additional cushioning and vibration resistance.
The goal of this analysis is to evaluate the vibration behavior of the board under real-world conditions, including its natural frequencies, mode shapes, and structural integrity when subjected to dynamic forces. The results will help optimize the material properties and structural design for better vibration absorption and durability.
