Bending of ring sandwich plate with light filler lying on elastic foundation is considered. For the description of kinematics of package with asymmetrical thickness the broken normal hypothesis was accepted. Reaction of foundation was described on the base of Winkler’s model. Combined equations of equilibrium and analytical solutions via displacement were received. Numerical ...

The article deals with some peculiarities of teaching calculating engineering task solutions to students on the bases of Mathcad.

These presented the particular features of developed software for organization all types of training work in the course «The theory of mechanisms and machines» - training, control of the knowledge, laboratory works, course designing.

h was developed computer model of single graphite atomic layer (graphene) crystal lattice on basis of valence-force-field approach. One performed computational experiments to determine mechanical cluiracteristics (linear elasticity modulus, crosscut compression coefficient, shear modulus) according to graphene particles dimensions. One realized comparison present results with ...

The correlation analysis of weight values of direction vectors and their order numbers of normalized vector model for objects under investigation is proposed. The experimental results of construction of the regression line are represented, as well as ones for calculation of theoretical-correlation ratio, similarity measure and classification of objects under investigation for a ...

The main limitation of assembly of the connections formed by mechanic pressing-in are noted, the new engineering solution on hydropress disassembly connections is described, the basic theoretical relations of process of a hydrothrust in a part jointing with guaranteed interference are adduced.

The method for а quantitative estimation of efficiency of running systems of vehicles for curvilinear motion, taking into account the deviation of vectors of driving wheels tractive forces from the direction determined a driver by means of turning steering wheel, is offered. Results of application of the developed method for an estimation of efficiency of running systems AWD ...

Methods of computational mechanics solve a problem of definition of external critical pressure of an envelope of the boiler of the tankcar in view of change of its width.

In this paper the simpe optimization problem of laminate discontinued rocks is considered. The paper presents some possible formulations of optimal structural design problem based on probabilistic approaches due to possible incompleteness of information concerning crack size, location and orientation. Using these approaches optimal designs for laminate rocks approximated to the ...
