The study of phononic materials and structures is an emerging discipline that lies at the
crossroads of vibration and acoustics engineering and condensed matter physics. Broadly …

In a standard design practice, it is often necessary to assemble engineered structures from
individually manufactured parts. Ideally, the assembled system should perform as if the …

The vibration responses of structures under controlled or ambient excitation can be used to
detect structural damage by correlating changes in structural dynamic properties extracted …

Natural biological systems can always demonstrate amazing properties or performance
subject to external excitation. The nonlinear damping characteristics of a passive bio …

Since Lord Rayleigh introduced the idea of viscous damping in his classic work" The Theory
of Sound" in 1877, it has become standard practice to use this approach in dynamics …

In the last few decades large research efforts have been devoted to the development of
methods for automated detection of damage and degradation phenomena at an early stage …

Close modes are much more difficult to identify than well-separated modes and their
identification (ID) results often have significantly larger uncertainty or variability. The …

Resonant elastic metamaterials are artificial material systems that exhibit unique dynamical
properties shaped by the intrinsic interaction between resonances and traveling dispersive …

In recent decades, nonlinear damping identification (NDI) in structural dynamics has
attracted wide research interests and intensive studies. Different NDI strategies, from …

It is common for dispersion curves of damped periodic materials to be based on real
frequencies as a function of complex wavenumbers or, conversely, real wavenumbers as a …
