The dynamic stability of a coupled two-degrees-of-freedom system subjected to parametric excitation by a harmonic action superimposed by an ergodic stochastic process is investigated. For the stability analysis, the ...

An approach is proposed to determination of effective characteristics of nanocomposites with using the known methods of micromechanics. An irregularity of distribution of discrete links between a nanofibers and a polymeric ...

With using the approaches of linearized solid mechanics, the axisymmetric problem on interaction of periodic system of coaxial disc-shaped cracks of radial shear in the infinite pre-stressed material is solved. Two ...

The equations of plane vertical motion are obtained for a hybrid model of mechanical system consisting of the horizontally placed string and the suspended at some its point two-link pendulum. The conditions of asymptotical ...

The modes and frequencies of natural vibrations of elastic ring are determined numerically within the framework of the boundary problem for corresponding differential operator of the 6th order. The ring is fixed at one ...

The method of calculation of critical loads of stiffened cylindrical shells is suggested. The shells are subjected of combined loading (external pressure and longitudinal axial loads). An effect of influence on critical ...

The stability of equilibrium state of layered bodies is studied for biaxial loading. It is assumed that deformation is absent in the layer plane. The three-dimensional linearized theory of stability jointly with the model ...
