    Opis:
    Large demand for bulk of sapphire optical products, which are widely used as illuminators, optical windows in aviation and aeronautics etc., generates the inquiry of effective production of high quality industrial crystals. The technology of crystal growth with the horizontal single crystal sapphire crystallization method is based on putting the crystal seed into the front of the crucible resistant to temperatures up to 2150°C. Without encompassment of the production technology of this special container made from thin molybdenum sheet is not realistic to consider the productive exploitation of horizontal crystallization systems in engineering practice. This paper presents the analysis of the possibility of the local resistance of molybdenum sheet heating by its deep drawing to obtain better drawing properties by increased blank temperature.

    Opis:
    In this project thesis, initial blank shape optimization of a twin elliptical cup to reduce earring phenomenon in anisotropic sheet deep drawing process was studied .The purpose of this study is optimization of initial blank for reduction of the ears height value. The optimization process carried out using finite element method approach, which is coupled with Taguchi design of experiments and reduced basis technique methods. The deep drawing process was simulated in FEM software ABAQUS 6.12. The results of optimization show earring height and, in addition, a number of design variables and time of process can be reduced by using this methods. After optimization process with the proposed method, the maximum reduction of the earring height would be from 21.08 mm to 0.07 mm and also it could be reduced to 0 in some of the directions. The proposed optimization design in this article allows the designers to select the practical basis shapes. This leads to obtain better results at the end of the optimization process, to reduce design variables, and also to prevent repeating the optimization steps for indirect shapes.

    Opis:
    The numerical results of superplastic punchless deep drawing of the Ti-6Al-4V titanium alloy were presented in this paper. The material behavior subjected to the forming process was characterized by deformation-microstructure constitutive equations including the grain growth. Superplastic stress-strain characteristics used in the numerical simulations were computed with the application of authorial program. The explicit integration scheme is used in solving differential equations. The numerical simulations of the super-elastic deep drawing were made with finite element method analysis. The von Mises stress distribution in the blow-forming process was obtained. The possible faults of extrusions caused by the improper load history as well as unsuitable pressure were also presented in this paper. The numerical simulations included in this research allow for the proper choice of material and drawing parameters which can help to optimize the superplastic forming process.
