### Some aspects of the geometry of the surfaces with the system of plane coordinate lines

Ivanov V.N.

#### Abstract

In the article, the geometry of the surfaces with the system of the plane coordinate lines is investigated. The common vector formula of these surfaces is received. The formulas of the coefficients of the quadratic forms are presented too. The conditions, when of the plane coordinate lines are lines of the principle curvatures of the surface, are received. The subclass of the surfaces with the system of the plane coordinate lines in the normal plane of the directrix curve is investigated. The formula of the Monge's ruled surfaces is received on the base of the common formula. The drawings of the Monge's ruled surfaces made in MathСad system are shown.

### NUMERICAL MODELING OF DEFORMATIONS OF THE INHOMOGENEOUS VISCOELASTOPLASTIC SOIL FOUNDATION

Kurachka K.C.

#### Abstract

The paper is dedicated to the creation of the mathematical model of deformations of the inhomogeneous viscoelastoplastic soil foundation. The algorithm, which based on the finite elements method, and the software is developed for numerical modeling viscoelastoplastic deformations of inhomogeneous ground bases. By means of the developed software research of presented mathematical model is carried out.

### MECHANICS: A PROBLEM - AN IDEA - A PRACTICE

Yakupov N.M.

#### Abstract

Диалектику познания и развития можно проследить, прослеживая цепочку решения той или иной задачи: «проблема - идея - практика». Именно такой естественной и диалектичной цепочки пытался придерживаться автор.

### on the calculation of composite beams on two-parameter elastic foundations

Filatov V.V.

#### Abstract

This article describes application of the composite bar and plate theory developed by A.R. Rzhanitsyn for calculating composite beams on two-parameter elastic foundations. Difference form of SUPROX method is used to generate some numerical algorithm. The calculation of composite beam on elastic foundations illustrates a simple and fast-convergence solution

### THE ACCOUNT OF DISPLACEMENT OF THE FINAL ELEMENT AS RIGID WHOLE IN MIXED FORMULATION FEM

Gureeva N.A., Klochkov J.V., Nikolaev А.P.

#### Abstract

The volume finite element is developed for calculation of covers of rotation in shape hexahedron with central unknown persons in a kind a component of a vector of moving and a component tensor strains. For expression the component of a vector of moving of an internal point of a finite element and its component tensor strains through central unknown persons was used a way of interpolation vector and tensor fields three linear by form functions that has allowed to consider implicitly displacement of a finite element as the rigid whole. For formation of a matrix of deformation hexahedron the variation principle in the mixed formulation was used. On an example efficiency of the offered way of approximation of required sizes as vector and tensor fields in comparison with traditional way of approximation of required sizes as scalar fields is shown.

### SPATIAL COMPELLED VIBRATIONS OF PIPELINE UNDER INTERNAL PRESSU

Khakimov A.G., Shakiryanov M.M.

#### Abstract

Investigation is focused on spatial nonlinear compelled vibrations of a double support pipeline affected by variable internal pressure. The dependencies have been obtained between the amplitude of pipe torsional and flexural vibrations and the values of static and dynamic components, circular frequency and initial internal pressure. It was shown that in the presence of resistance forces the amplitudes of pipe angular and flexural motions are essentially lower as compared to what takes place in the absence of these forces. It was found that a relatively small increase in the pressure static component can cause a considerable increase in the amplitudes of both angular and flexural motions.

### CONSTRUCTIVE AND TECHNOLOGICAL FEATURES OF APPLICATION OF FACING PANELS OF VENTILATED FACADES FROM THE SYNTHETIC GRANITE

Rogov V.A., Svintsov A.P., Sidorenko S.N.

#### Abstract

The researches which have been carried spent at People's Friendship University of Russia have allowed to receive composite structures of a synthetic granite which on the architectural and building properties can simulate natural граниты and мраморы. Results of development of technical and technological decisions on the device of ventilated facades of buildings and constructions with application of facing panels from a synthetic granite are submitted.
