Linear Elasticity (3D)

This lecture covers the concept of linear elasticity in three dimensions, focusing on stress and strain tensors, internal forces, and the stress-strain relationship according to Hooke's law. It delves into the isotropic and homogeneous materials, discussing the stress and strain fields, constitutive laws, and material properties. The lecture also explores the application of superposition in stress analysis and the importance of shear stress and strain in linear materials.
