← ScienceWhich outcome occurs when rapid cycling stresses wind turbine blades past the fatigue endurance limit?
A)Progressive accumulation of microscopic structural damage✓
B)Sudden transition to a crystalline blade phase
C)Increased surface albedo from thermal stress
D)Elevated natural frequency from blade deformation
💡 Explanation
Fatigue failure occurs because cyclic loading causes stress concentration at microstructural flaws, leading to crack initiation and propagation, which is the mechanism of fatigue. The outcome, therefore, is microscopic damage, which accumulates with each cycle, rather than sudden crystallization under stress or a shift in surface albedo.
