Abstract

In this study, a time reversal mirror is used to remotely focus symmetric or antisymmetric modes in a plate of arbitrary shape without the need of precise knowledge about material properties and geometry. The addition or subtraction of the forward motions recorded by two laser beams located on both sides of the plate allows, respectively, to focus a symmetric or an antisymmetric mode. The concept is validated using experimental and numerical analysis on an aluminum plate of complex machined geometry which exhibits various thicknesses as well as a bi-materials zone. Finally, the limitations and possible ways to overcome them are then presented.

Three-dimensional solutions for the thermal buckling and sensitivity derivatives of temperature-sensitive multilayered angle-ply plates

Journal Article Noor, A K ; Burton, W S - Journal of Applied Mechanics (Transactions of the ASME, Series E); (United States)

Analytic three-dimensional thermoelasticity solutions are presented for the thermal buckling of multilayered angle-ply composite plates with temperature-dependent thermoelastic properties. Both the critical temperatures and the sensitivity derivatives are computed. The sensitivity derivatives measure the sensitivity of the buckling response to variations in the different lamination and material parameters of the plate. The plates are assumed to have rectangular geometry and an antisymmetric lamination with respect to the middle plane. The temperature is assumed to be independent of the surface coordinates, but has an arbitrary symmetric variation through the thickness of the plate. The prebuckling deformations are accounted for.

Influence of anisotropy on the dispersion characteristics of guided ultrasonic plate modes

Journal Article Li, Y ; Thompson, R B - Journal of the Acoustical Society of America; (USA)

Dispersion curves are developed for elastic wave propagation in an anisotropic plate of monoclinic or higher symmetry. Emphasis is placed on analytic expressions for various features. Generalization of the isotropic Rayleigh--Lamb dispersion relations are derived for the cases of (a) propagation along a material symmetry axis and (b) propagation in a general direction. Examination of the high-frequency limit of the lowest symmetric and antisymmetric mode dispersion curves yields expressions for the half-space surface or Rayleigh wave velocity. It is shown that the dispersion curves for these modes can exhibit multiple crossings in approaching this limit, and an analytic solution ismore »« less

Damage imaging in a laminated composite plate using an air-coupled time reversal mirror

Journal Article Le Bas, P. -Y. ; Remillieux, M. C. ; Pieczonka, L. ; ... - Applied Physics Letters

We demonstrate the possibility of selectively imaging the features of a barely visible impact damage in a laminated composite plate by using an air-coupled time reversal mirror. The mirror consists of a number of piezoelectric transducers affixed to wedges of power law profiles, which act as unconventional matching layers. The transducers are enclosed in a hollow reverberant cavity with an opening to allow progressive emission of the ultrasonic wave field towards the composite plate. The principle of time reversal is used to focus elastic waves at each point of a scanning grid spanning the surface of the plate, thus allowingmore »« less

Tandem-mirror trapped-particle modes at arbitrary collisionality

Journal Article Cohen, R H ; Nevins, W M ; Berk, H L - Phys. Fluids; (United States)

Tandem-mirror trapped-particle modes are studied in a model system consisting of two connected square wells representing the solenoid and the end cells. Collisions are described by a Lorentz operator. A dispersion relation that is valid for arbitrary ..nu../..omega.. (..omega.. = wave frequency, ..nu.. = collision frequency) is derived. Four limits are investigated. When epsilonequivalent..nu..R/sub am//..omega.. <<1+p/sub i//p/sub e/, where R/sub am/ is the mirror ratio separating electrons trapped in the anchor from those passing to the solenoid and p/sub e/ and p/sub i/ are the fractions of passing electrons and ions, collisions destabilize a trapped-particle mode that is stable inmore »« less

Performance of a continuously rotating half-wave plate on the POLARBEAR telescope

Journal Article Takakura, Satoru ; Aguilar, Mario ; Akiba, Yoshiki ; ... - Journal of Cosmology and Astroparticle Physics

A continuously rotating half-wave plate (CRHWP) is a promising tool to improve the sensitivity to large angular scales in cosmic microwave background (CMB) polarization measurements. With a CRHWP, single detectors can measure three of the Stokes parameters, I, Q and U, thereby avoiding the set of systematic errors that can be introduced by mismatches in the properties of orthogonal detector pairs. We focus on the implementation of CRHWPs in large aperture telescopes (i.e. the primary mirror is larger than the current maximum half-wave plate diameter of ~0.5 m), where the CRHWP can be placed between the primary mirror and focalmore »« less
