Deep drawing is a complex process influenced by the geometric parameters of the die-punch system. In the present paper we study the behavior of the semi-finished product, in the process of drawing deep cylindrical parts, using the finite element method and the software package of the ANSYS program. In order to reduce the cost and design time, an analysis of the variation of the radius connection is carried out, resulting in low energy consumption, using the finite element method. By analysing the radius of connection of the plate, we identify future directions useful in substantiating the elaboration of a judicious experimental program and optimizing the geometric shape of the finished parts.

The paper defines the average and local soil storage coefficients, for a soil with relatively shallow water table. By means of an adequate law for the suction distribution on soils level and certain parametrical models for the moisture retention curve of soil, the analytical equations for these storage coefficients were determined. Theoretical results are to be applied for a case study and on the basis of a pertinent analysis, and some recommendations were made for the practical use of formulae proposed for the storage coefficients.

The current paper describes the concept and the mathematical models axed upon flow transport and transport of pollutants in the aquifer inside a metallurgical waste hall. Then, using a complex of basic data related to a representative case study-several information being achieved by systematic measurements, for long period, throughout ten drillings-and the pack of FEFLOW 5.1 programmes, the dispersion of an uppermost pollutant (the anion SO 4) has been numerically simulated, for the entire observing period. Therefore, it was emphasized the pollutant flow rate led through by the phreatic aquifer exploited by the subsurface exhausters water.
