“…3 The first nonlinear ultrasonic method used is the scaling subtraction method (SSM). 7 It consists of successively sending two pulses, one low amplitude A ref assumed linear and one larger amplitude A i assumed nonlinear. By rescaling both responses and computing the difference, the full nonlinearity is obtained.…”

Recently the concept of probing nonlinear elasticity at an interface prosthesis/bone has been proposed as a promising method to monitor the osseointegration/sealing of a prosthesis. However, the most suitable method to achieve this goal is a point of debate. To this purpose, two approaches termed the scaling subtraction method and the cross-correlation method are compared here. One nonlinear parameter derived from the cross-correlation method is as sensitive as a clinical device based on linear elasticity measurement. Further, this study shows that cross-correlation based methods are more sensitive than those based on subtraction/addition, such like pulse inversion and similar methods.

“…NEWS with TR procedure has been recognized as a useful tool for non-destructive testing (cracks detection) of various solid materials, such as complex composites. During the pioneering work in bubbly liquids [15], efficiency of TR-NEWS methods have been numerically demonstrated [30] and extended [31][32][33] in complex structure for crack identification and detection.…”

“…18 In the former, in particular, when the excitation amplitude is amplified by a factor k, the output response is not simply amplified correspondingly. These features are exploited by the scaling subtraction method (SSM) 19,20 and nonlinear loss of reciprocity (NLR) based methods. 21 The goal of this paper is first to show the existence of strain amplitude thresholds for nonlinearity detection.…”

Wheel/rail noise generation due to nonlinear effects and parametric excitationNonlinear effects on the propagation of elastic waves in hysteretic media are of great importance, with applications in imaging and monitoring evolution of damage/phase transitions/biological features. However, excitation amplitudes are an issue in order to improve performances of the techniques. Noise effects in the signals can be stronger than the generated nonlinear effects, thus rendering difficult the nonlinear analysis. Here, we analyze the link between the amplitude threshold for detection of nonlinear effects and different kinds of noises, which might be present in experiments. We also discuss the implications in the intrpretation of experiments. V C 2013 American Institute of Physics. [http://dx.
