Measurement of cyclic stress in service is important as it can confirm service loading for comparison with theoretical loading predictions. Measurement of cyclic stresses can allow the estimation of fatigue life and be used to organise repair and maintenance schedules.

StressProbe can be used to measure principal stress direction during cyclic loading, enabling the determination of force paths. This provides useful insight into the stress distribution in a component or structure.

StressProbe can be used to measure cyclic stresses in structures of any age. It does not need surface contact, being capable of measuring through surface coatings up to 5mm. StressProbe can measure at frequencies up to 33Hz, and can measure stress changes as small as 1MPa depending on the steel type used. StressProbe can only be used on ferro-magnetic materials.
