Nonlinear Non-Destructive Testing of ship hull composites
Independent thesis Advanced level (degree of Master (Two Years))Student thesis
Further development of an existing nonlinear ultrasound Non-Destructive Testing method is performed. The Nonlinear Wave Modulation Spectroscopy method is developed into an automated non-contact testing method. The method detects nonlinearities, such as cracks and delaminations, in a test object. In this thesis the method is automated and used for crack detection in ship hull composites. A non-contact testing prototype is built that uses the criterions of an open resonator to set a test object in resonance. Further, the interesting physical properties of the ship hull composites are studied.
