crack propagation

Crack propagation refers to the process in which a crack in a material grows over time, often leading to failure. When a crack forms, stress around it increases, causing the crack to widen and extend. Factors like material properties, environmental conditions, and external forces influence this growth. In everyday life, this concept can be observed when a small scratch on glass extends into a larger break. Understanding crack propagation is crucial in engineering and safety, as it helps predict material failure and establish the durability of structures, ensuring they can withstand various stresses and strains.
