Highly nonlinear solitary waves for the detection of localized corrosion
Smart Materials and Structures, 2020Abstract This paper investigates the application of highly nonlinear solitary waves as a nondestructive evaluation method to detect localized corrosion in metallic structures. An experiment was conducted by using chains of monoperiodic particles in contact with a steel plate subjected to localized accelerated corrosion.

Axial stress determination using highly nonlinear solitary waves
The Journal of the Acoustical Society of America, 2018This article presents a nondestructive evaluation (NDE) method to infer the neutral temperature and the axial stress in thick beams. The method relies on the propagation of highly nonlinear solitary waves generated at one end of a chain of spherical particles in a dry point contact with the beam to be evaluated.

Highly Nonlinear Solitary Waves for the Inspection of Adhesive Joints
Experimental Mechanics, 2012In this paper we propose the use of highly nonlinear solitary waves (HNSWs) to monitor the curing process of an adhesive layer utilized to bond two aluminum sheets, and to inspect an adhesively-bonded aluminum lap-joint. HNSWs are mechanical waves that can form and travel in highly nonlinear systems, such as a chain of spherical particles where they ...

Highly Nonlinear Solitary Waves for the NDT of slender beams
2015Slender beams subjected to compressive load are common in civil engineering. The rapid in-situ measurement of this stress may help preventing structural anomalies. In this article we describe the coupling mechanism between Highly Nonlinear Solitary Waves (HNSWs) propagating along a granular system in contact with a beam subjected to thermal stress.

Highly Nonlinear Solitary Waves to Estimate Orientation and Degree of Anisotropy in Rocks
Materials Evaluation, 2021This paper delves into the use of highly nonlinear solitary waves for the nondestructive identification and characterization of anisotropy in rocks. The nondestructive testing approach proposed expands upon a technique developed recently by some of the authors for the nondestructive characterization of engineering materials and structures.

Interaction of highly nonlinear solitary waves with large plates
2015 Symposium on Piezoelectricity, Acoustic Waves, and Device Applications (SPAWDA), 2015Due to geometric nonlinearity, stress waves of one-dimensional granular chains behave as highly nonlinear solitary waves. Those waves can support a high level of amplitude over a long distance and have an important engineering value for detecting structure properties. Deflection can be caused by the impact of a granular bead with large plates. Based on

Nondestructive testing of concrete using highly nonlinear solitary waves
Nondestructive Testing and Evaluation, 2016AbstractIn this article, we describe the capability of a nondestructive evaluation (NDE) method at determining the strength of concrete surfaces. The method uses highly non-linear solitary waves (HNSWs) propagating inside a metamaterial in contact with the concrete to be tested.

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 ...
