Performance of a macro-FEM approach using global interpolation (Coons') functions in axisymmetric potential problems
Ch. Provatidis,A. Kanarachos +1 more
TL;DR: In this article, a global functional set is extended to axisymmetric potential problems and the main idea is to build up isoparametric finite elements based on the interpolation formula developed by S.A. Coons for arbitrary-shaped CAD patches.

Arbitrary precision frequencies of a free rectangular thin plate
TL;DR: A variational method developed by the authors and named whole element method (WEM) is used to find the arbitrary precision frequencies of a rectangular thin plate (within the Germain-Lagrange theory) having its four borders free of constraint as discussed by the authors.
Design of a Lightweight, Electrodynamic, Inertial Actuator with Integrated Velocity Sensor for Active Vibration Control of a Thin Lightly-Damped Panel
TL;DR: In this paper, a lightweight inertial actuator, with integrated velocity sensor, for the implementation of velocity feedback control, in lightly-damped panels, is presented, and the main design issues are discussed starting from the characterization of the electromagnetic device which has been optimised using a finite element analysis to produce the maximum design force of 3N for a given weight of the inertial mass of 20g and input power constraints.

Numerical simulation of the fluid structure interaction in a tube array under cross flow at moderate and high Reynolds number
Vilas Shinde,Thibaud Marcel,Yannick Hoarau,Thibaut Deloze,G. Harran,Franck Baj,Jerome Cardolaccia,Jean-Paul Magnaud,Elisabeth Longatte,Marianna Braza +9 more
TL;DR: In this paper, the onset of fluid-elastic instability is analysed for different structural parameters, Scruton number and reduced velocity, for a configuration of (4×5) cylinders in static conditions as well as for the vertical free motion of one of the central cylinders in one DOF (Degree Of Freedom).

Research on the February 18, 1996 earthquake in the caves of Saint-Paul-de-Fenouillet area, (eastern Pyrenees, France)
TL;DR: In this paper, the authors investigated eight caves near Saint-Paul-de-Fenouillet after the magnitude 5.2 earthquake of February 1996 which occurred in the Eastern Pyrenees (France) and caused moderate damage at the ground surface.
