Tomographic Imaging of Structural Damage in Plates (2007-2009)
Abstract
The proposed project promotes a fundamental advance in the application of plate-wave ultrasonic diffraction tomography for the quantitative reconstruction of laminar defects by investigating experimental and theoretical aspects of wave-mode coupling at defects. Previous attempts have ignored mode coupling effects and therefore do not properly describe a major physical effect of the wave scattering problem. The aims of the project are: 1) to quantify mode coupling parameters for certain generic forms of laminar damage; and 2) to quantify the influence of mode coupling on the imaging performance of early stages of structural damage.
