Noninvasive low-cycle fatigue characterization at high depth with photoacoustic eigen-spectrum analysis
In this work, photoacoustic eigen-spectrum analysis was proposed for noninvasively characterizing the mechanical properties of materials. We theoretically predicted the relationship between the photoacoustic eigen-spectra of cylindrical optical absorbers and their mechanical properties. Experimental...
