Repair and replacement of critical and major components in industrial plants is costly and can lead to significant loss of production. Testing of such components in a laboratory setting provides the opportunity to assess their condition, predict failure modes and validate design modifications to increase reliability and support life extension. Mechanical response to loads is of particular concern for the operation of these components. Custom built test fixtures were used to replicate and exceed operational loads in the laboratory and allow accurate measurements of displacements and strains experienced by the equipment. These measurements relied on a variety of sensors and techniques, including strain gauges, LVDT and digital image correlation (DIC). Most notably, DIC was able to overcome some of the traditional sensors' limitations by measuring strain fields in highly deformed regions. This presentation includes examples of unique test set-ups used to support the continued operation of large components.
