The mathematical model of graphen nanostructure containing a cut is constructed and realized in package Mathematica. Dependences of forces arising in valence bonds at loading and Young modulus from length of defect are investigated. It is shown, that at edge of a cut forces grow in some times. Young modulus decreases almost in two.

There is helical motion of biological environment in the cardiovascular system and others transporting systems. The member of the Academy N. Dobrecov reported about that discovery in his paper in 2003. The basis of such motion is transporting canals walls interaction with the medium due to torsion wave that is generated by helical and muscular elements. The walls of arteries have ...

The six degree offreedom spatial movement system has been examined. Algorithms and simulation programs for direct and inverse kinematic problems solving of spatial mechanism are presented. As a result of computer simulation the movement system's actuator spatial motion capabilities are obtained and investigated.

In the present paper the algorithm of calculation of velocities and accelerations of components of mechanical system in Mathematica package Mechanical systems is submitted. The example of calculation of velocities and accelerations of elements of brake draft of a back suspension bracket of the automobile is resulted.

Numerical analysis of three dimensional coin tossing is presented. Coin model includes air resistance. It is assumed that the air resistance force is proportional to the velocity. Comparison of results with and without the air resistance shows that the air friction may be nonnegligible.

3-D finite-element model of rigid body with crack was created in ANSYS program. Stress intensity factors were calculated for three loading situations. Comparison of the solutions of the classical crushing mechanics problems with computer simulation results instill confidence in the validated modeling. ANSYS mode was used for exploration of the stressedly-deformed mode in the ...

Buildings and structures are affected externally by the blowing of wind in several aspects. Aerodynamic effects are the most important for multy-stored buildings. The aerodynamic effect is concerned with the configuration of the air flow in the building domain. This configuration determines the distributions of pressure and velocity on the building surfaces. In paper are presented ...

ANSYS doesn’t fit to analyze dynamics/kinematics of the mechanical mechanisms and ADAMS doesn’t fit for finite element analyzing the parts of these mechanisms. The paper deal with combining method of computer simulation programs ADAMS and ANSYS to analyze and simulate mechanisms with flexible components, approving the method feasible through simulating example.

Calculation of statically indefinable rod systems is considered at a stretching-compression in case ofjoint action of mechanical, temperature loadings and discrepancy of manufacturing.

Heat irradiation elements as rule have the shape of the cylinders. Tensely-strained state for entire cylinder under acting pressure, irregular warming and radiation are analysed in this article. The construction mathematical models and programming of the numerical method for task solving. Checking the right variant of the received results. The importance of radiation action on ...
