The present study is aimed at expanding flexibility and . In this paper we perform the corresponding analysis and formulate criteria determining the minimal size of detectable cracks. The relation of the nonlinear - modulation technique to the linear frequency-shift technique is discussed. The analysis is particularly focused on the nonlinear - modulation resonance technique.
It is based on rather general properties of the defects consistently predicted by various rigorous cracks models. One of the easiest ways to produce an AM signal is by the product modulator. For linear perturbations to remain valid on large scales, we need to renormalize perturbations at higher . Novel nonlinear - modulation methods for crack detection are discussed. The approach is based on the so-called cross-modulation effect consisting of the modulation transfer from an intensive, initially slowly amplitude-modulated stronger (pump) excitation to the probe signal.
Many wave phenomena in physics are described by weakly nonlinear nearly monochromatic solutions in the form of modulated wave packets. The examples include ocean waves as well as waves in optics and in plasmas. New nonlinear terms that originated from non-elongation constraint and continuation analysis of the beam compose the second part of nonlinearities.
The effects of these nonlinearities in amplitude modulation AFM have never been studied in previous researches. In energy point of view, these nonlinear terms which are .
