Dear all,

*Dr. Öğr. Üyesi Önder Türk*  from Gebze Technical University will give a
talk titled *“** Modal Analysis of Incompressible Elastic Waves Based on a
Stabilized Finite Element Method*  *”* on 30th October, at 14:00. All
interested are invited.

Abstract: Modal analysis is a typical approach employed to approximate
vibration problems of elastic materials. The key idea is to assume a
harmonic behaviour for the displacement utilizing the second order time
derivatives in the inertia term, and thus to transform the problem into an
eigenvalue problem. The set of equations is form identical to the Stokes
equations which govern the incompressible creeping flow of viscous fluids,
and is a constituent of Navier-Stokes equations. In this talk, will
concentrate on a stabilized finite element  method formulated in a
variational multiscale framework where the continuous space is approximated
by a direct sum of the finite element space and its orthogonal complement.
We shall show that the numerical procedure provides a reasonably realistic
description of the eigenspectrum of the associated operator affirming that
there are no spurious eigenvalues. Once the eigenspace has been built, the
time approximation to the solution of the continuous problem is obtained
making use of a few modes of the whole set, those with higher energy. The
presentation will include several theoretical and numerical results from
joint works with Daniele Boffi and Ramon Codina.
