Nonlinear Acoustic Metamaterials and Sound Bullets
Chiara Daraio
Assistant Professor of Aeronautics and Applied Physics, Caltech
We develop new acoustic metamaterials based on "engineered" nonlinear periodic crystals across different dimensional scales. We aim at providing the fundamental understanding of how stress waves propagate in uniform, heterogeneous, ordered and disordered media and to exploit such knowledge for the creation of new materials and devices (for example, for vibration absorption and non-destructive evaluation). One-dimensional chains of particles exhibit a highly nonlinear dynamic response, allowing a completely new type of wave propagation that has opened the door to exciting new fundamental physical observations (i.e. energy trapping phenomena, stress redirection and anomalous reflections). This talk will focus in particular on the discovery of a new dramatic acoustic focusing effect, and the formation and propagation of compact acoustic pulses (sound bullets) in solid and fluid media, enabled by a tunable, highly nonlinear acoustic lens. The lens consists of ordered arrays of granular chains. The amplitude, focal length, and the spatial positioning of the sound bullets can be controlled by varying static precompression on the chains. We support our findings with theory and numerical simulations, and corroborate the results experimentally with photoelasticity.

Composites with Unusual Properties, Including Negative Refraction Index or Negative Effective Mass-density and Effective Stiffness

Abstract
Electromagnetic (EM) and elastic properties of composites can be controlled by suitable design of their microstructures. In particular, composites can be created that display unusual properties, such as negative index of refraction, or simultaneously negative effective mass-density and effective stiffness over certain frequency windows. For suitably long wave-lengths, such composites are macroscopically homogeneous.
Periodic arrays of inductive elements such as thin straight wires, loop-wires, and coils can modify the effective electric permittivity of a composite and even make it negative. A similar effect on magnetic permeability can be achieved through use of high capacitance elements. When both the permittivity and permeability are negative, the composite displays negative index of refraction.
In the range of acoustic wave frequencies, elastic composites with periodic microstructures exhibit band gaps. They also can have pass bands with negative phase but positive group velocities. This then implies simultaneously negative effective mass-density and stiffness for the composite, over the corresponding frequency range. In addition, since wave energy travels with the group velocity, and since group velocity is strongly direction-dependent in highly anisotropic composites, microstructurally heterogeneous (but macroscopically homogeneous) anisotropic composites offer opportunities to control and manage stress-wave propagation.
The lecture will examine various aspects of this rich research area.

Experimental characterization of buffer layer structures associated with extreme wall stress events in a smooth wall turbulent boundary layer
Three dimensional velocity distributions and wall stresses are measured concurrently in the inner part of a smooth wall turbulent boundary layer using digital holographic microscopy. Conditional sampling based on local shear stress maxima and minima reveals two types of dominant buffer layer structures. The first develops as spanwise vorticity lifts abruptly from the wall, creating initially a vertical arch, which is then stretched to forms a pair of counter rotating vortices inclined at an angle exceeding 45°. A wall-stress minimum forms under the point of initial lifting, while two stress maxima develop 35 wall units downstream due to vortex-induced entrainment. The second characteristic structure is a single, slightly inclined but predominantly streamwise vortex. It generates a strong elongated stress maximum on one side, and a weak minimum on the other. The presentation will conclude with several other examples of applications of cinematic digital holography, such as breakup of crude oil droplets treated with dispersants, as well as swimming behavior and interactions among organisms located in dense suspensions.

Application of X-ray CT in Geotechnical Engineering
June 8, 2009 at 4:00 PM — CEE Conference Room A230 Technological Institute

Professor of Soil Mechanics and Geotechnical Engineering
Kumamoto University, Japan

Although X-ray CT scanner has been widely used as a medical diagnosis, this apparatus became popular even in the field of engineering. We started to use X-ray CT scanner which is called "industrial X-ray CT scanner" from 1996. Since then, we have conducted a large number of studies and activities concerning the application of X-ray CT for geomaterials. The industrial CT has much more energy compared with the medical one, so that more accurate CT data should be obtained. As far as the research topics are concerned, we have done a lot of studies from soil mechanics to geotechnical engineering such as characterization of deformation and failure of soils, that of seepage behavior in the soil, evaluation of tunnel failure and its reinforcing methods, characterization of bearing capacities of shallow and deep foundations, and others. These are not only visualization of the behavior but also its quantitative discussion. This center deals with more wide range of research fields such as not only Geotechnical Engineering and Rock Engineering, but also Applied Coastal Engineering, Geoenvironmental Engineering, Thermal Flow Engineering, Material Science, and even Archaeology.
In this lecture, basic feature of X-ray CT scanner is introduced and some of our application studies so far in the field of soil mechanics and geotechnical engineering are presented. And at the end, our new research center, "X-Earth Center" will be introduced briefly.
