Laser induced highly nonlinear solitary waves for structural NDE
SPIE Proceedings, 2010This paper describes the generation and propagation of highly nonlinear solitary waves (HNSWs) in a chain of steel beads excited by means of laser pulses. Ablative generation of mechanical stress was induced on the bead at one end of the chain in order to enhance the amplitude of the stress waves generated. Compared to the use of a mechanical striker,

The interaction of highly nonlinear solitary waves and viscoelastic half-space
2017 Symposium on Piezoelectricity, Acoustic Waves, and Device Applications (SPAWDA), 2017The method of nondestructive testing (NDT) using the coupling of highly nonlinear solitary waves in one-dimensional particle chains and structures is a new research hotspot which is gradually improved. Based on properties of solitary wave, we investigate the coupling mechanism between highly nonlinear solitary waves and viscoelastic half-space and ...

Highly nonlinear solitary waves-based sensor for monitoring concrete
SPIE Proceedings, 2011This paper describes the application of a novel actuator/sensor technology for monitoring concrete at early age. A device is designed to generate and detect highly nonlinear solitary waves (HNSWs) in a chain of steel beads. Two experiments were conducted. In the first experiment, the propagation of the HNSWs in the chain was recorded. In particular,

Weak bond detection in composites using highly nonlinear solitary waves
Smart Materials and Structures, 2017We experimentally investigate a diagnostic technique for identifying a weak bond in composites using highly nonlinear solitary waves (HNSWs). We set up a one-dimensional chain of granular crystals, consisting of spherical particles with nonlinear interactions, to generate HNSWs.

Recent advancement on the NDE of structures by means of highly nonlinear solitary waves
SPIE Proceedings, 2012In this paper, we propose the use of highly nonlinear solitary waves (HNSWs) for the nondestructive evaluation of aluminum lap-joints bonded by high-strength two ton epoxy. A HNSW transducer was used to generate and detect the propagation of incident and reflected HNSWs.

Use of highly nonlinear solitary waves for the assessment of dental implants
The Journal of the Acoustical Society of America, 2011This paper presents a noninvasive technique based on the propagation of highly nonlinear solitary waves (HNSWs) to monitor the stability of dental implants. HNSWs are mechanical waves that can form and travel in highly nonlinear systems, such as one-dimensional chains of contacting spherical particles (i.e., granular crystals).

Experimental parametric analysis of an energy harvester based on highly nonlinear solitary waves
Journal of Intelligent Material Systems and Structures, 2016We investigate experimentally five different designs of an energy harvester based on mechanical vibration and highly nonlinear solitary waves. The harvester consists of a metamaterial formed by granular chains, an oscillator that taps the metamaterial, a solid in contact with the metamaterial, and a piezoelectric element glued to the solid. The overall
