Time-Dependent Deformation

Time-dependent deformation refers to how materials change shape or size over time when subjected to stress. This phenomenon includes processes like creep, where materials slowly deform under a constant load, and relaxation, where they experience reduced stress over time. This behavior is significant in engineering and construction, as it affects the durability and performance of structures. Understanding time-dependent deformation helps engineers design safer and more reliable buildings, bridges, and other materials by accounting for how their properties will change throughout their lifespan.
