Extension of self-heating-based vibrothermography (SHVT) as a non-destructive testing method for inspection of plate-like composite structures

• Dates: 2022-2024
• Place: Silesian University of Technology

• Funding source: Silesian University of Technology - Excellence Initiative

The primary objective of this project is to implement and extend the self-heating vibrothermography NDT technique for detecting and localizing damage in plate-like (2D) composite structures made of polymer matrix materials. The project consist of theoretical analysis of the phenomenon of self-heating during resonant vibrations, numerical simulation of the self-heating effect to support the experimental studies, and finally experimental validation of the technique used on plate-like structures with damage. Within the project, appropriate damage quantification algorithms are developed to enhance detectability of damage as well as quantify identified damage.
