Lecture
This lecture covers the concepts of deformation and creep in materials, discussing topics such as energy expended per cubic meter for deformation, heat generation, and the behavior of materials under stress. It also explores the effects of temperature and stress on material properties, as well as the mechanisms of creep and fracture. The lecture delves into the significance of mechanical tests, including the creep test, and the analysis of creep curves. Additionally, it examines the properties of ceramics, polymers, and metals, highlighting their mechanical behavior, density, and melting points. The lecture concludes with a discussion on the nature of atomic bonds in ceramics and the structures of amorphous materials.
