ZGV Lamb modes for fatigue monitoring
20/06/18 15:07
Many engineered objects endure stress throughout their lifetimes, typically leading to material fatigue and failure, which can turn to tragedy, as in the Versailles rail accident of 1842. Thus … Read More…
Cubic H2O ice investigation with TDBS technique
31/10/17 14:49
We investigated experimentally and theoretically elastic properties and phase transitions of cubic H2O ice at room temperature and high pressures between 10 and 82 GPa. … Read More…
Monitoring of phase transition with TDBS technique
27/05/17 15:18
Picosecond acoustic interferometry is used to monitor in time the motion of the phase transition boundary between two water ice phases, VII and VI, coexisting at a pressure of 2.15 GPa when compressed in a diamond anvil cell at room temperature. Read More…
ZGV Lamb modes for flaw detection in composite materials
30/09/16 15:01
Shaping of the generation laser beam allows better generation of the zero-group-velocity (ZGV) Lamb modes and shows their potential to detect subsurface flaws in composite material plates. Read More…
