Structural Mechanics: Basics and Applications

This lecture introduces the basics of structural mechanics, covering topics such as the nature of forces, equilibrium, and the behavior of materials under load. It explores concepts like stiffness, strength, and toughness in engineering materials, as well as the different classes of materials. The lecture delves into the roots of mechanics, including point particle mechanics and stress-strain relationships. It also discusses failure mechanisms in structures, such as elastic and inelastic failures. Additionally, it touches on advanced topics like hyperelasticity, viscoelasticity, plasticity, fatigue, and fracture mechanics. The history of mechanics, from Leonardo da Vinci to modern contributions, is also presented.
