Generation and Detection of Higher Harmonics in Rayleigh Waves Using Laser Ultrasound
This research studies higher harmonics of Rayleigh surface waves propagating in nickel base superalloys. Rayleigh waves are used because they carry most of the energy and travel along the surface of a specimen where fatigue damage is typically initiated. The energy concentration near the free surfac...
