In this paper, we discuss two problems concerning scattering and localisation of flexural waves in structured elastic plates. Firstly, we compare the scattering amplitudes of waves in a thin plate, generated by a point source, due to a single mass and to a large number of smaller masses, having the same equivalent mass and located around a circle. We show that in the second case, the scattering can be reduced, in particular in the medium- and high-frequency regimes.

I have a few positions (funded by NSF, AFRL, and/or ARO) for MS or PhD (preferred) students at the University of Tennessee Space Institute (UTSI) and University of Tennessee Knoxville (UTK) in the following two topics:

1. Elastodynamic metamaterials: Characterization of dispersive constitutive equations and simulation of the material with overall properties in the time domain (TD), analysis of the effect of disorder and material nonlinearities (e.g. fracture) in their performance, etc.

We discuss the state of the art and recent advances on the interplay between viscoelasticity and mechanical instabilities and metamaterials.

In situ dendrite reinforced Bulk Metallic Glass matrix composites (BMGCs) are known to overcome poor ductility and fracture response exhibited by monolithic bulk metallic glasses (BMGs). In this paper (Shear fracture in bulk metallic glass composites) recently published by our group in Acta Materialia, we report mode I and mode II fracture experiments on the above in situ BMGCs containing transforming and non-transforming dendrites.

If you have ever had to study and teach classical mechanics, then one of the challenges is to explain the equivalences of distinct formulations of the equations of motion for discrete mechanical systems. It is not transparent, particularly in the presence of constraints, how the Newton-Euler equations, Lagrange’s equations, Gibbs-Appell equations, Maggi's equations, Kane’s equations, Boltzmann-Hamel equations, and several other fomulations, are equivalent.
