Abstract

Ultrasonic guided waves have been demonstrated as a promising tool in nondestructive evaluation (NDE) and structural health monitoring (SHM), especially for plates and plate-like structures. However, many plate-like structures subject to NDE and SHM are curved. The curvature plays an important role in guided wave propagation. The objective of the work presented in this paper is to investigate the influence of curvature on guided wave propagation. A semi-analytical finite element (SAFE) technique is employed to analyze the dispersion curves for plate-like structures with different curvatures. The changing of the wave structures with curvature is investigated as well. Physical insight on the dispersion curve variations introduced by the plate curvature variation is obtained through wave structure analysis.
