2-D and 3-D problems of the elasticity problems for incompressible materials are considered. Solving these problems using the finite-element method results in solving the linear algebraic equations system with sparse matrix. For incompressible materials this system is the system with a saddle point (i.e. the matrix eigen values have different signs). Thus, applying such solving methods as the conjugate gradient method and the generalized minimal residual method is impossible. Uzawa method is suggested to be used for such problems. It is an iterative process, and at each iteration it is necessary to solve the linear algebraic equations system, but this system is without a saddle point. The different variants of Uzawa algorithm are realized within CAE Fidesys software package, and their efficiency is compared in the article.

Keywords: theory of elasticity, incompressible materials, finite-element method, Uzawa algorithm, iteration methods for systems of linear algebraic equations

This paper presents a comparative analysis of the effectiveness of the method Cuthill-McKee algorithm and fill-reducing ordering of a sparse matrix, based on multi-level nested dissection paradigm, developed at the Department of "Computer Science and Engineering," University of Minnesota. For short, we shall call the algorithm Cuthill-McKee CM, and the algorithm of the University of Minnesota — NodeND (Node nested dissection). This article uses a modification of the CM algorithm — RCM (reverse Cuthill-McKee), because in practice the reverse numbering index allows you to get a greater advantage than using a direct algorithm CM. The reason for using these algorithms are high speed computational algorithm, as it is necessary to solve the system proximal to the diagonal, the great acceleration of algorithms for solving FE problems using technology such as CUDA

The nano-catalyst ceria (CeO2), activated by Pt nanoparticles, is known for being prospective and efficient material widely used in catalysis, fuel elements, and sensors. One of the most up-to-date methods of catalysts' reasearch is X-ray absorption spectroscopy (XAS) that is sensitive to the chemical state of catalyst's active centers [1,2]. Using XAS in the fluorescense detection mode at CeL1 line with high precision we studied electronic structure of Pt-activated nanoparticles of ceria at various redox conditions. In order to detect partial X-ray fluorescence yield the emission line CeLγ3 was used, which allowed us to increase spectral resolution. We researched local atomic and electronic structure of the materials under study. Oxygen vacansies were found to appear on the nanoparticles surface of ceria at 5% CO He atmosphere. Theoretical modeling of the obtained spectra at CeL1-edge demonstrated good agreement with experiment.

"This article is devoted to the development of the method for modeling elements of microsystems technology(MST) of membrane type. In this paper perforated membranes are considered and the impact of perforation on the mechanical properties of the membranes is examined. In numerical simulations of the elements it is proposed to use the equivalent mechanical parameters of perforated membranes obtained at the initial stage of the simulation. This will allow to obtain find the optimal parameters of perforation, reduce the time and resource modeling of MST elements. To test the technique numerical experiments were conducted for the two square membranes with sides 1.5 and 3 mm fixed on the contour of the same thickness. We studied the influence of the size of the perforation on the equivalent Young's modulus of the perforated membrane. "

Operation of sylvinite ore desliming is an important step of potassium chloride production by floatation method. It is known that ultrasonic treatment is applied to increase the efficiency of insoluble rest separating from an ore. The purpose was to establish kinetic regularities of the insoluble rest removal from sylvinite ore crystals of the same particle size distribution. Investigations were carried out with mechanical stirring and sonication of varying intensity. It is established that process of sylvinite ore desliming occurs in the diffusion mode. Application of ultrasonic treatment allows to intensify process in 2-4 times as compared with mechanical desliming. Influence of sylvinite ore treatment parameters to chemical composition changing of the insoluble rest is defined. It is shown that sonication for 90 seconds leads to removing carbonates from ore crystals withal concentrating of the iron compounds.
