Fatigue and Damage Tolerance is a specialized discipline that includes assessment of material response to the aircraft mission cycle, most notably cyclic loading, and uses principles of material science and fracture mechanics to enable establishment of effective design criteria and life management plans for critical aircraft components to ensure flight safety.

Key elements of this discipline include fatigue and fracture mechanics analysis supported by material testing, modeling and probabilistic assessment. This versatile framework has a broad range of practical applications, including aging aircrafts, composite aircraft structures, qualification of new materials and manufacturing technologies, risk assessment and field failure investigations.

To support the above objectives, Fatigue and Damage Tolerance discipline interfaces with a number of other technical areas including Metallurgy, Advanced Composites, Nondestructive Inspections, Health Monitoring and Safety Analysis.
