Pitting occurs when repeated contact stresses exceed the compressive yield strength of the gear material. Over time, microscopic cracks form on the tooth surface, leading to material flaking. AGMA 218.01 provides equations to calculate the contact stress number ( ) and compares it to the allowable contact stress ( sacs sub a c end-sub Bending Strength (Root Fatigue)
