Abstract

Recently diffusion joining and friction stir joining have been used for a solid state bonding. They can be affected by impurity of the atmosphere, temperature etc, so a closed crack may arise. This research investigates applicability of a new method by nonlinear acoustics to detection of closed cracks. Numerical analysis and experiment were conducted on a specimen with a closed crack. As a result, higher harmonics appeared in received signals. The longer the crack was, the larger the amplitude of higher harmonics became. These results show a possibility of nondestructive testing by nonlinear acoustics.
