Monitoring the hydration of cement using highly nonlinear solitary waves [PDF]

open access: yesNDT and E International, 2012
In this paper we present a nondestructive evaluation technique based on the propagation of highly nonlinear solitary waves (HNSWs) to monitor the hydration of cement. 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). In the present

Propagation of highly nonlinear solitary waves in a curved granular chain [PDF]

open access: yesGranular Matter, 2013
We assemble granular chains composed of spheres of uniform diameter in different curved configurations. We study the properties of highly nonlinear solitary waves traveling in the curved channels as a function of the curve angle and of the radius of curvature, using experiments and numerical simulations.

Highly nonlinear solitary waves in chains of hollow spherical particles [PDF]

open access: yesGranular Matter, 2013
We study the dynamic response of one- dimensional granular chains composed of uniform hollow spheres excited by an impulse, and we observe the formation and propagation of highly nonlinear solitary waves. We find that the dynamics of these solitary waves are different from the solitary waves forming in chains composed of uniform solid spheres, because ...

Highly Nonlinear Solitary Waves for the NDT of slender beams [PDF]

open access: yes, 2015
Slender 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.
