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 ...

The generalized form of the principle of virtual work is obtained, when the virtual work is considered as a time integral of virtual power. The corresponding this form Euler – Lagrange equation includes the divergence of ...

A technique for analysis of non-stationary vibrations of cylindrical shells, which interact with flowing liquid, under action of external periodical pressure with slowly changing frequency is proposed. A numerical study ...

30 сентября 2010 г. научная общественность Института механики им. С.П.Тимошенко Национальной академии наук Украины отмечает юбилейную дату со дня рождения доктора физико-математических наук Елены Ивановны Беспаловой.

Basing on new approach, an effect of boundary conditions on effectiveness of active damping of forced resonance vibrations of a viscoelastic orthotropic plate is studied. The cases of hinged and rigid fixing the plate ...

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 ...

A theory of long-term damageability is suggested for the granular composite materials with allowance for temperature effect. The process of damage of composite components is modeled by forming the stochastically arranged ...

A plane problem on tension of a body with crack with piece-wise diagram of deformation is reduced by the Fourier-transform method to the system of nonlinear algebraic equations. The body contains a crack. Basing on ...

The stress intensity factors distributions (CIF) of three types – the opening fracture mode, the longitudinal and transverse shear modes – are studied for the bimaterial with penny-shaped crack at interface under harmonic ...

An equation of the finite element method, which describes the large strains in the tensor-matrix form, is proposed. The equation is simplified and then modified with aim to describe the deformation of bodies from ...
