Masters

Xavier Maldague (Co-supervisor)
Approach: Vibrothermography stimulated by ultrasound is a relatively recent non-destructive test technique which allows defaults to be detected which were until now undetectable with other conventional optical techniques. This technique is efficient for the detection of micro cracks and micro delaminations in complex materials developed in the aerospace industry.
The figure above illustrates the detection of nano-cracks using a phasegram at 2 Hz.
