Fatigue Cracks

Fatigue cracks form in a material in response to weakening from repeated loading and unloading or other dynamic stresses. The micro cracks that initially form can grow and affect the structural integrity of a material or component, often leading to greater damage. Fatigue cracks are the most common cause of drill stem failure, and can occur at stress levels well below the normal operating stress in most drill stem components.
