Lecture

Linear Elasticity and Atomic Structure

Description

This lecture covers the linear elasticity properties of materials, including stresses, strains, and examples of elastic properties. It explains the origin of material elasticity related to the atomic structure, rigidity, and loading cases. The lecture delves into the deformation of bodies under external forces, the dimensionless nature of deformations, and the relationship between forces and deformations. It also explores the types of bonds in solids and their connection to material rigidity. Additionally, it discusses the elastic properties of springs, interatomic bonds in crystalline materials, and the measurement methods for elastic properties like the modulus of elasticity and Poisson's ratio.
