Which risk increases when a turbine blade approaches resonant frequency?

💡 Explanation

Accelerated fatigue crack propagation occurs because resonance amplifies vibrational stresses causing increased fatigue. The blade experiences excessive oscillation due to the frequency matching natural modes causing fatigue, therefore this explains the fatigue risk rather than alternative oxidation or yield strength changes.
