Mechanical Dynamics

My current research interests include vibration and acoustic testing based on laser-induced plasma, damage detection, modal analysis, polymer gels, and soft actuators.
> Hemispherical breathing mode speaker using a dielectric elastomer actuator
> High spatial and temporal resolution measurement of mechanical properties in hydrogels by non-contact laser excitation
> Damage detection in transparent materials using non-contact laser excitation by nano-second laser ablation and high-speed polarization-imaging camera
> Nano-second laser-induced plasma shock wave in air for non-contact vibration tests
> Lamb wave generation using nanosecond laser ablation to detect damage
> Non-destructive firmness assessment of apples using a non-contact laser excitation system based on a laser-induced plasma shock wave
> Estimation of the auto frequency response function at unexcited points using dummy masses
> Dynamic characterizations of underwater structures using non-contact vibration test based on nanosecond laser ablation in water: investigation of cavitation bubbles by visualizing shockwaves using the Schlieren method
> Non-contact acoustic tests based on nanosecond laser ablation: generation of a pulse sound source with a small amplitude
> Acoustic testing in a very small space based on a point sound source generated by laser-induced breakdown: stabilization of plasma formation
