Technology mechanical point-shock engraving on photo printer for printing on products is particularly popular among specialists designers because the entire process of creating images and computer training to the engraving is very creative and at the same time allows you to make adjustments to the customer at any stage without much effort or loss of quality and time. To solve this problem it is necessary to analyze the causes of the marriage; determine the types of marriage by using technology of printing on the surface of the product mechanical point-impact photo printer and suggest methods to eliminate it.

We obtained the solution of the optimization problem for the step-parallel beam with constant width of the cross-section. The problem was solved by minimizing the strain energy while the volume of beam is constant. The solution was made for the case of simple support at the ends and evenly distributed along the length load. We introduced the parameter α, which is the ratio of height of the average part to a height of side parts. The optimal value of α was found. At this value the stiffness of the beam is maximum at constant volume. The obtained beam of maximum stiffness is not equal strength.

We solved the problem of optimizing the gable beam by minimizing the strain energy at constant volume. The problem reduced to an integral equation for determining the optimum angle of the beam. This equation was solved numerically by the method of bisection. Integral was calculated using the method of trapezoids. Solution was made in software package Matlab. The optimum angle depends on the width of the cross section b, and the volume of the beam. It was found that with increasing of width of the cross section the optimum tilt angle decreases. Also the volume increases by increasing the width of the beam.

The resolving equations for the calculation of the stability of polymer compressed rods with the creep using Galerkin method are obtained. The problem is solved in the case of a simply supported pivotally-rod having an initial bending in the plane of the lower stiffness, and in the case of off-center application of force. Galerkin method used in combination with the finite element method, that is the shape functions are taken as the basis functions . The solution is made numerically, using the software package Matlab. There are two variants considered: a variant of the rod with constant and variable in length stiffness. It is shown that for rods with variable cross-sections and the same mass, a critical time has increased by almost 4.5 times. The solution for the rods of constant cross section agrees well with the solutions obtained by the method of finite differences. This may indicate the reliability of the proposed method

This article related to the technological problem. Books and manuscripts are subjected to natural aging due to the fragility of the raw materials, the deterioration of the conditions of storage, as well as losses of fragments due to repeated or careless operation. Therefore, for libraries, archives and museums is particularly important in matters of preservation of documents not only the process of conservation, but the recovery of the lost fragments.

  The article shows that the viscoelastic behavior of polymers is well described by a nonlinear generalized Maxwell equation, generalized Russian scientists GI Gurevich In this paper, based on the results of experimental studies of the isothermal relaxation of thermal stresses presented a method to determine the relaxation parameters of the equation. The experiment was carried out on thin-walled tubes, with rigidly clamped ends. Heating or cooling from initial temperature to a final temperature (the temperature relaxation time) was carried out at a constant rate of heating (cooling) in a linear fashion. This work shows that the linearized theory does not give correct results.
