摘要：
This paper presents a tunable ultrasonic lens for the flexible control and modulation of Lamb waves. The lens is comprised of layered slice structures using Shape Memory Alloy (SMA) which could change its material properties under thermal loads. Numerical investigations on the wave dispersion characteristics demonstrate the tuning capability of wave speeds in the slice waveguide. Harmonic and transient dynamic modeling results further present the wave steering and focusing phenomena to a desired direction and focal point, covering a scanning area. Such a capability possesses great application potential to enhance the performance of Lamb wave based SHM and NDE systems.
