Morphology
The phrase is directly compositional: 'fatigue' denotes material weakening from repeated stress and 'crack' denotes a split, so 'fatigue crack' straightforwardly means a crack caused by fatigue. This modifier+head compound follows a common morphological pattern found across languages and is predictable for a learner who knows both constituent words, even if the term is somewhat technical.
Etymology
The term fatigue crack comes from the idea that metal can get 'tired' after many pushes or bends, and then a small crack appears because of that fatigue. So, the phrase means 'a crack caused by repeated stress'.
