Re: lamb wave prob
Hi Yasin,
Lamb Waves are generated when you impinge the surface of your part with a conventional wave (typically longitudinal) at the appropriate angle to generate the desired Lamb mode in your part. Therefore, conventional angle beam probes can be used if you select the correct angle and frequency. This selection involves understanding the testpiece geometry and the many possible Lamb modes that can be generated in it. Then you can select the necessary test configuration (probes, frequency, etc.).
It is also possible to use variable angle probes having broad bandwidth so that many modes can be generated by changing angle and frequency content.
More recently, phased array probes are being used to select modes electronically.
But, once again, your first step is stating your test piece and flaw geometries.
Regards,
Paul
