Vortex dissipation and level dynamics for the layered superconductors with impurities

, 2001
We study parametric level statistics of the discretized excitation spectra inside a moving vortex core in layered superconductors with impurities. The universal conductivity is evaluated numerically for the various values of rescaled vortex velocities ...

Vibration Analysis of a Three-Layered FGM Cylindrical Shell Including the Effect Of Ring Support

Open Physics, 2019
In this work, we study vibrations of three-layered cylindrical shells with one ring support along its length. Nature of material of the central layer is a functionally graded material (FGM) type. The considered FGM is of stainless steel and nickel.
