Information : Non-Contact Stress Analysis
A thermal image analyzer manufactured by Spate is used by Bell Helicopter Textron, Inc. (BHTI) as a non-contact stress analysis tool. A part is placed under cyclic loading and infrared detectors measure temperature changes over the surfaces of the part. The steady-state temperatures are filtered from the signal to reveal temperature variations over the part. These temperature variations directly correspond to stress fields on the surface of the part. This analysis tool enables the designer to identify stress concentrations and stress levels on the surface of complex parts and assemblies.
