This paper begins with a quick survey of potential space applications and brief review previous experiments on the shape control spherical shell reflector thin film PVDF-TrFE. Next, problem thermal sensitivity is addressed numerically; it found that, because large expansion active material, surface figure error generated by linear gradient unimorph considerable its correction requires voltages....

Abstract A quadrilateral flat-shell element is developed for analysing the deflections, stresses and natural frequencies along with their allied mode shapes of cylindrical, spherical, conical shell panels made up layered composite sandwich material. The (DKZigTS1) based on zigzag theory has seven local as well global DOF per node. concept obtaining transformation matrix used transforming action...

We derive the off-shell scattering matrix for a spherical scatterer. The result obtained generalizes the off-on-shell matrix commonly used in the theory of scalar waves propagation in random media.

In this paper, the temperature dependence on optical absorption cross section of the core shell bimetallic nanoparticles (NPs) is investigated in quasi static approximation. Temperature dependence of the plasmon resonance is important issue because of recent applications of NPs of noble metal for heat treating of cancer and the computer chips. The effect of temperature on surface plasmon resona...

This paper is concerned with the extension of existing nonlinear physical modeling sound synthesis cymbals to that involving dynamics washers supporting center and sticks/mallets striking cymbals. The body a cymbal physically modeled as shallow spherical shell its governing equation discretized in space using finite difference method, was implemented research. In addition, washer, related suppo...
