Introduction to Creep

In this video, we explore the phenomenon of creep in materials science, explaining how it is a time-dependent deformation that occurs under an applied load below the material's yield strength. Creep typically happens at elevated temperatures but can also occur at room temperature in certain materials like lead or glass. This slow process leads to a time-dependent increase in length, potentially causing rupture if unaddressed. We discuss the typical creep curve, its characteristics, and its significance in applications such as turbine blades in jet engines and power plants, highlighting the importance of understanding and managing creep to ensure the durability and safety of materials in high-stress, high-temperature environments.
