Abstract
A method for determining the presence of damage in a structure includes applying energy to the structure to induce tension shockwaves in the structure. The method also includes detecting sound waves caused by the tension shockwaves using at least one acoustic emission sensor on the surface of the structure. Additionally, the method includes determining the presence of damage in the structure due to the applied energy based on detected sound waves.
