Accredited Fatigue Testing with Precision and Speed
AADFW Inc. provides metallurgical fatigue testing services to evaluate how metallic materials perform under repeated or cyclic loading. Fatigue testing determines how many stress cycles a component can endure before cracks initiate or failure occurs. This data is critical for validating materials used in safety-critical applications such as aircraft structures, pressure systems, and high-stress mechanical components.
Engineers rely on fatigue testing to simulate real operating conditions where materials experience repeated loading over time. By understanding fatigue life and crack behavior, manufacturers can design components that maintain structural integrity throughout their service life.
AADFW operates as a NADCAP accredited laboratory with ISO/IEC 17025 certification, delivering precise fatigue testing with faster turnaround times than many large global testing labs.

Why Fatigue Testing Matters
Many mechanical failures occur not from a single overload event but from repeated cyclic stresses that gradually produce microscopic cracks. Over time, these cracks grow until the material can no longer sustain the load.
Fatigue testing provides engineers with critical performance data including:
• Cycles to failure under controlled stress conditions
• Fatigue strength and endurance limits of materials
• Crack initiation and crack propagation behavior
• Stress-life and strain-life performance data
• Material performance validation under cyclic loading
• Compliance data for engineering standards and design validation
This information allows manufacturers to predict service life and reduce the risk of unexpected mechanical failure.
