efnistýr
efnistýr is an Icelandic word that translates to "material fatigue" in English. It refers to the progressive and localized structural damage that occurs when a material is subjected to repetitive stress. This phenomenon is distinct from static failure, which occurs when a material breaks under a single, sufficiently large load. Material fatigue typically begins as a small crack, which then grows over time with continued cyclic loading, eventually leading to catastrophic failure.
The concept of efnistýr is crucial in engineering and materials science, particularly in the design of structures
