• Introduction
Definition of fatigue in materials
Fatigue in concrete refers to the progressive and
cumulative damage that occurs in the material under
repeated loading or cyclic stress. It is a phenomenon
where the strength and stiffness of concrete
gradually decrease over time when subjected to
repetitive or fluctuating loads.
