Le résumé fourni par la source
This study numerically investigates the effectiveness of pulsed infrared thermography (PIT), an active infrared imaging technique, for detecting subsurface defects and damage in ultra-high-molecular-weight polyethylene (UHMWPE) materials, which are widely used in helmets and armor systems. To understand the heat transfer mechanisms involved in PIT inspection, numerical models were developed incorporating bottom-flat-hole (BFH) defects in homogeneous panels and delamination defects in composite laminates. Parameters such as defect size, depth, and aspect ratio were analyzed to assess the sensitivity and limitations of the PIT technique. All simulated defects were successfully detected, confirming PIT’s potential as a powerful non-destructive evaluation method. Beyond structural health monitoring, the underlying optoelectronic principles of PIT, such as infrared emission, photothermal conversion, and time-resolved optical detection highlight its relevance to broader optoelectronic applications, including thermal imaging sensors, smart materials, and photonic diagnostic systems. This cross-disciplinary insight opens the door for PIT-inspired innovations in advanced optoelectronic diagnostics and material-integrated sensing platforms.
