Actuators for the generation of highly nonlinear solitary waves [PDF]
Review of Scientific Instruments, 2011 In this paper we present the design of two actuators for the generation of highly nonlinear solitary waves (HNSWs), which are mechanical waves that can form and travel in highly nonlinear systems.

Highly nonlinear solitary waves in heterogeneous periodic granular media [PDF]
Physica D: Nonlinear Phenomena, 2009 We use experiments, numerical simulations, and theoretical analysis to investigate the propagation of highly nonlinear solitary waves in periodic arrangements of dimer (two-mass) and trimer (three-mass) cell structures in one-dimensional granular ...

Highly Nonlinear Solitary Waves for the Assessment of Dental Implant Mobility. [PDF]
J Appl Mech, 2013 In this paper we present a noninvasive technique based on the propagation of highly nonlinear solitary waves (HNSWs) to monitor the stability of dental implants. HNSWs are nondispersive mechanical waves that can form and travel in highly nonlinear systems, such as one-dimensional chains of spherical particles.

Highly nonlinear solitary waves in chains of ellipsoidal particles [PDF]
Physical Review E, 2011 We study the dynamic response of a one-dimensional chain of ellipsoidal particles excited by a single compressive impulse. We detail the Hertzian contact theory describing the interaction between two ellipsoidal particles under compression, and use it to

Detecting the Presence of High Water-to-Cement Ratio in Concrete Surfaces Using Highly Nonlinear Solitary Waves [PDF]
Applied Sciences, 2016 We describe a nondestructive evaluation (NDE) method based on the propagation of highly nonlinear solitary waves (HNSWs) to determine the excess of water on the surface of existing concrete structures.

Coupling mechanism of highly nonlinear solitary waves with damaged composite material plates [PDF]
Composites and Advanced Materials, 2021 The coupling interaction between nonlinear solitary waves in one-dimensional granular chains and damaged composite material plates is considered. Based on Hertz contact law and meso-mechanical model of stiffness reduction of composite material plates when the fiber breakage is the main damage mode, the coupled differential equations of particle chains

Long time dynamics of highly concentrated solitary waves for the nonlinear Schrödinger equation [PDF]
Journal of Differential Equations, 2015 In this paper we study the behavior of solutions of a nonlinear Schroedinger equation in presence of an external potential, which is allowed to be singular at one point. We show that the solution behaves like a solitary wave for long time even if we start from a unstable solitary wave, and its dynamics coincide with that of a classical particle ...

Interaction of highly nonlinear solitary waves with linear elastic media [PDF]
Physical Review E, 2011 We study the interaction of highly nonlinear solitary waves in granular crystals, with an adjacent linear elastic medium. We investigate the effects of interface dynamics on the reflection of incident waves and on the formation of primary and secondary reflected waves. Experimental tests are performed to correlate the linear medium geometry, materials,

Site-Specific Quantification of Bone Quality Using Highly Nonlinear Solitary Waves [PDF]
Journal of Biomechanical Engineering, 2012 Osteoporosis is a well recognized problem affecting millions of individuals worldwide. The ability to diagnose problems in an effective, efficient, and affordable manner and identify individuals at risk is essential. Site-specific assessment of bone mechanical properties is necessary, not only in the process of fracture risk assessment, but may also be
