Parallelization of BICG-STAB method for solution of unsymmetric systems of linear equations arising in finite element discretization
Sousedík, B. ; Novotný, Jaroslav
We describe parallelization of BICG-STAB method for solution of unsymmetric systems of linear equations arising in finite element discretization using MPI and OpenMP.
Solution of incompressible flow using FEM adjusted to singularity
Šístek, J. ; Burda, P. ; Novotný, Jaroslav
We describe solution of incompressible fluid flow using the finite element method on meshes adjusted to singularity.
R-waves in an orthotropic elastic half-plane
Červ, Jan
The properties of Rayleigh waves in an orthotropic elastic half-plane are studied in the paper. It is supposed that body axes x, y and principal materials axes 1,2 coincide. the laminate Aramid is then considered as an examle of typical orthotropic material it has been proven that R-waves propagate in principal directions nondispersively.
Waves in thin orthotropic elastic plate
Volek, J. ; Červ, Jan ; Valeš, F.
The analytical solutions based on Kirchhoff and Rayleigh approximations of a thin elastic orthotropic plate under transverze load are discussed in the paper. The results are compared with those obtained by means of FEM.
Numerical and experimental investigation of stress wave propagation in orthotropic strip
Zemčík, R. ; Červ, Jan ; Laš, V.
Our intention is to assess the credibility of such homogenization in the case of stress wave propagation induced by impact and apply the experience gained to the non-stationary state of comlex laminated composites together with the consideration of material damage.
