Non-Invasive Testing of Physical Systems Using Topological Sensitivity

A review of available results on non-destructive testing physical systems, using the concept topological sensitivity, is presented. This mathematical tool estimates sensitivity a set measurements in some given sensors, distributed along system, to defects/flaws that produce degradation system. Such manifests itself properties The good performance this general purpose post-processing method reviewed and illustrated applications involving testing. These include structural health monitoring, considering both elastodynamic ultrasonic guided Lamb waves active infrared thermography. Related methods can also be used other fields, such as diagnosis/prognosis engineering devices, which considered.
