Opis:: In this paper, a numerical solution of mass transfer effects on an unsteady free convection flow of an incompressible electrically conducting viscous dissipative fluid past an infinite vertical porous plate under the influence of a uniform magnetic field considered normal to the plate has been obtained. The non-dimensional governing equations for this investigation are solved numerically by using the Ritz finite element method. The effects of flow parameters on the velocity, temperature and concentration fields are presented through the graphs and numerical data for the skin-friction, Nusselt and Sherwood numbers are presented in tables and then discussed.

Opis:: The issue of Ritz vectors and their advantages is well-known in the field of structural engineering. This study deals with Ritz analysis and its experimental support. To that end, two different precast concrete molds were handled. Experiments were performed under vibration with the use of a computer-based data acquisition system. Transducers were used to measure displacement histories on the mold. Three dimensional finite element (3D FEM) simulation modeling of the concrete mold was carried out to obtain deflection histories on the mold. The computed displacement histories were compared with the experimental testing results. The comparisons show that the experimental and numerical results are compatible.
