microdamaged
Microdamaged is an adjective used to describe a material, structure, or tissue that has sustained damage at the microscopic level. Such damage may not be visible to the naked eye but can be detected with microscopy or imaging techniques. Common forms of microdamage include microcracks, microvoids, dislocations, or subtle collagen or fibre damage that precedes macroscopic failure.
In engineering materials, microdamage arises from fatigue, impact, or thermal cycling. Small cracks or voids accumulate
Detection and implications: Microdamaged regions may be monitored with electron microscopy, micro-computed tomography, acoustic emission, or
