High Cycle Fatigue Performance in Laser Shock Peened TC4 Titanium Alloys Subjected to Foreign Object Damage
During their service, titanium alloys are likely to suffer from the foreign object damage (FOD), resulting in a decrease in their fatigue strength. Laser shock peening (LSP) has been proved to effectively incr...

Experimental determination of some nonlinear elements of third sound dynamics
The frequency shifts of third sound resonances during free decay are observed to have a quadratic dependence on the amplitude of the wave motion. An unambiguous measurement of amplitude allows for quantitative...
