The article proposes the derivation of resolving equations for the bending of triangular finite element of plate with regard to creep. In deriving of the equations we use Lagrange variational principle. The problem is reduced to a system of linear algebraic equations. Creep contributes only to the right side of the system of equations. These equations allow to calculate the plates of arbitrary shape, taking into account the viscoelastic properties of the material. An example of the calculation for a rectangular plate of a secondary polymeric PVC, hinged along the contour and loaded uniformly distributed over the area load is presented. As a law establishing a link between stress and creep deformation we used nonlinear equation of Maxwell-Gurevich. Calculations were performed in Matlab software package. The graphs of change in time of deflection and stresses are presented. Stress during creep vary slightly, a difference between the stresses at the beginning and end of creep process does not exceed 6%. The result of numerical calculation of the maximum deflection value at the end of creep is different from the theoretical on 0.26%.

Keywords: creep, finite element method, bending of plates, polymers, Maxwell-Gurevich equation, long cylindrical rigidity

Are given the results of studies on the creation of samouplotnyayushchikhsya fine-grained fibrobetonov on the withdrawals of lithotrity with the application of a polyfunctional additive D -5. Are developed the compositions of samouplotnyayushchikhsya fine-grained fibrobetonov with the application of a basaltic fibre, which make it possible to considerably decrease the expenditure of cement and to improve the characteristics of fine-grained concrete mixture and concrete. The use of a polyfunctional additive D -5 in the mixtures makes it possible to increase the strength properties of fine-grained fibrobetonov with a simultaneous improvement in the rheological characteristics of concrete mixtures. The replacement of cement to 10 % from the mass by ashes of fraction d0,14 mm in the fine-grained concrete mixtures does not cause noticeable reduction in the strength properties of concrete. Developed samouplotnyayushchiesya fine-grained fibrobetony possess the increased strength properties and have low prime cost due to the use of local raw material and withdrawals of lithotrity

The main target of sales policy in a competitive environment is customer funnel and customer loyalty. Sales approach involves encouragement of customers, vendors and business partners. Advertising is a means of a sales activity. While determining the most efficient way of distributing expenses for the purpose of advertising, it makes economic sense to use mathematical methods of programming and statistic analysis of target audience. It is able during the analysis to determine the most efficient time and location for ad placement, possible target audience and its income level. A method of calculating should be selected in order to gain more profit and incur less expenses. This is Fore and Malgrange method which allows to do so. Benefit of this method is optimality test in the process of decision making.

The dynamic model of continuous distribution process allowing on the basis of sampling in time to reduce the corresponding generalized dynamic task to a problem of vector conditional optimization is considered. By means of optimization of weight coefficients of the scalar criteria encapsulated in criteria rollup on the basis of the generalized functional ratio expressing understanding of an intercriteria compromise the possibility of establishment of the most acceptable quantitative preferences between alternatives is shown. The offered approach allows to regulyarizirovat algorithms of dynamic planning for single-product distribution systems, having eliminated the developed obvious dependence of optimization process and results of adoption of multicriteria decisions on expert procedures and heuristic factors.

Results of researches on improvement of quality of the brick made of clay Kagalnik-3 raw materials are presented. It is defined that raw materials contain a large number of particles less than 1 mm in size that complicates receiving press powder of the recommended granulometriya. In addition, because of high sensitivity of raw materials to drying, on samples there are drying cracks influencing durability and frost resistance. It is defined that for receiving qualitative products, except softer mode of drying, for increase in physico-mechanical characteristics it is necessary to add the mineral modifying additive to furnace charge, and to carry out preparation of press powder with preliminary plastic granulation of weight.
