Fatigue Crack Growth Testing

Fatigue crack growth tests characterize the rate at which pre-existing cracks in metals, ceramics, composites and other materials propagate as a function of a cyclic driving force, most commonly the range of applied stress intensity. Automation of crack size measurement is frequently done through compliance or potential drop techniques. Tests are often conducted in thermal and chemical environments that represent those seen in service to account for the synergistic effects these factors have on fatigue crack growth. Fatigue crack growth tests generate data that can be used as a basis for setting inspection intervals in components designed for damage tolerance.

MTS offers extensive expertise in fatigue crack growth testing and more than 40 years of experience in all varieties of fatigue testing. We also provide the advanced technology test professionals need to perform accurate, repeatable fatigue crack growth tests.
