Introduction to Structural Mechanics

This lecture introduces the fundamental concepts of structural mechanics, covering topics such as static approach, normal stresses, mathematical expressions, and applications in engineering. It explores the analysis of forces, equilibrium equations, and the determination of stresses and strains in structures. The lecture also delves into the use of finite element modeling for complex systems and the considerations for integrity criteria. Examples like bending beams and maximum load analysis are used to illustrate the concepts. The instructor discusses the constitutive law of elastic solids, internal forces in beams, and mechanical connections, emphasizing the importance of understanding reaction efforts and diagrams.
