This document provides an overview of structural dynamics and vibration. It classifies vibration based on excitation source as either periodic or random. It discusses different types of free vibration including underdamped, critically damped, and overdamped systems. Mass, stiffness, and damping are introduced as key agents in dynamics. Examples and references are provided for further reading on vibration modes, resonance, and experiments demonstrating vibration concepts.
