Materials Science: Mechanical Properties and Material Selection

This lecture covers the introduction to materials science, mechanical properties, and material selection for engineering applications. Topics include basic mechanical properties, case studies on material selection, behavior under static and dynamic loading, fracture mechanics, fatigue resistance, and composite materials. The instructor discusses the criteria for choosing materials for pressure vessels, emphasizing factors such as strength, ductility, toughness, and fatigue resistance. Practical examples, including the design of a pressure vessel, are used to illustrate the importance of material properties in engineering applications.
