Description

This lecture covers the concepts of elasticity and deformation in materials, including the types of polymers, structure of organic materials, stress-strain relationships, and the behavior of materials under tension, compression, and shear. It also discusses the anisotropy of elastic properties, measurement methods for elastic modulus and Poisson's ratio, and the relationship between Young's modulus, Poisson's ratio, and shear modulus. The lecture further explores the concept of yield strength, isotropic and anisotropic materials, and the storage of elastic energy in materials. Examples of materials with different elastic properties are provided, along with methods for measuring elastic properties using acoustic waves. The lecture concludes with a comparison of energy storage in materials during elastic deformation.
