摘要：
A numerical study is presented of the influence of plate curvature and taper on the transport of ultrasound guided wave signals for nondestructive evaluation (NDE) and structural health monitoring (SHM) applications. Model formulations for transmission at sharp transitions in plate curvature and thickness taper are summarized. Results are presented showing that transitions in plate curvature and tapered plate thickness have minimal effect on signal transmission efficiency when associated characteristic dimensions are large compared to plate thickness.
