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.

Detecting the Presence of High Water-to-Cement Ratio in Concrete Surfaces Using Highly Nonlinear Solitary Waves

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.

A Comparative Study on Three Different Transducers for the Measurement of Nonlinear Solitary Waves

Sensors, 2013
In the last decade there has been an increasing interest in the use of highly- and weakly- nonlinear solitary waves in engineering and physics. Nonlinear solitary waves can form and travel in nonlinear systems such as one-dimensional chains of particles,

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

Interaction of highly nonlinear solitary waves with thin plates

International Journal of Solids and Structures, 2012
AbstractWe investigate the reflection of highly nonlinear solitary waves in one-dimensional granular crystals interacting with large plates. We observe significant changes in the reflected waves’ properties in terms of wave amplitude and time of flight in association with the intrinsic inelasticity of large plates, which are governed by the plate ...

Chirped localized pulses in a highly nonlinear optical fiber with quintic non-Kerr nonlinearities

Results in Physics, 2022
We study the existence and propagation properties of chirped localized pulses in a highly nonlinear fiber medium exhibiting self-steepening, self-frequency shift, and quintic non-Kerr nonlinearities.

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. These waves are characterized by a constant spatial wavelength and by a tunable propagation speed, dependent on the wave amplitude. To date, the simplest and

A Comparative Study on Generation and Propagation of Nonlinear Waves in Shallow Waters

Journal of Marine Science and Engineering, 2023
This study is concerned with the generation and propagation of strongly nonlinear waves in shallow water. A numerical wave flume is developed where nonlinear waves of solitary and cnoidal types are generated by use of the Level I Green-Naghdi (GN ...
