Time-reversed Lamb waves 来自 NCBI 喜欢 0 阅读量: 183 作者:Ing, R.K,M Fink 摘要: Lamb waves are extensively involved in plate structure inspection because of their guided nature. However, their dispersive nature often limits their use in flaw detection. In this paper we show that the use...
The group velocities of the time-reversed Lamb waves in the acrylic tubes were measured by using the axial transmission technique. They decreased very slightly with increasing wall thickness, showing good agreement with the theoretical group velocity of the A0 Lamb wave in the acrylic plate. These...

Time reversed lamb wave based damage detection is very suitable for online Structural Health Monitoring (SHM). Non linear higher and sub harmonics are generated in the Lamb waves which are generated and sensed using partially de-bonded piezoelectric wafer transducers (PWT) from the host plate. ...

The device for estimating the cortical bone mineral density using the time-reversed lamb waves comprises: a lamb wave production unit; a lamb wave transmission unit; a lamb wave reception unit; a conversion unit; a time reversing unit; a signal processing unit; and a calculation unit.;...
Also, by radiating the time-reversed lamb waves to the shinbone, the present invention can calculate the transmission speed of SGW, which is closely related to the thickness of the cortical bone, and accordingly can predict the thickness of the cortical bone with high reliability.LEE, KANG IL...
