In this paper we review recent progress on the analysis, experimental exploration, and
application of elastic wave propagation in weakly nonlinear media and metamaterials. We …

This paper aims to explore the working mechanism of sandwich-like meta-plates by
periodically attaching nonlinear mass-beam-spring resonators for low-frequency wave …

Modelling and numerical simulation–based on the framework of the Local Interaction
Simulation Approach–was developed to have more insight into nonlinear attributes of …

This paper investigates the second-order harmonics generation associated with propagation
of Lamb wave in pre-stressed plates. The second-order harmonic phenomena appear in a …

The paper presents outcomes of a finite element (FE) study of acoustoelastic effect
associated with Lamb wave propagation in plates subjected to homogeneous bi-axial and …

Nonlinear ultrasonic guided waves are of great importance in structural health monitoring,
since they have both the large-area inspection capability of guided waves and the desirable …

Different from elastic waves in linear periodic structures, those in phononic crystals (PCs)
with nonlinear properties can exhibit more interesting phenomena. Linear dispersion …

Wave propagation and stopband behavior in square lattices hosting nonlinear resonators
made of suspended piezoelectric membranes with a central mass are investigated by …

Multiple scattering from a cluster of nonlinear point attachments on a beam is formulated and
analyzed. The nonlinear equation of motion is solved using a perturbation strategy. The …

Nonlinear shear horizontal guided wavefield is investigated analytically in plates. The major
focus is on the effect of nonlinear material parameters, excitation frequency, wave number …
