The asymptotic equilibrium equations of shells with geometric imperfections which take the interaction of buckling modes in a neighborhood of the critical point into account are derived. This derivation is based on the ...

A three-layer thick-walled cylinder with isotropic layers under a uniform axial end load is considered. In the exact statement, a problem on the influence of the thickness of layers on end effects is investigated, the total ...

It is shown that the stable and unstable limit cycles exist in the phase space of а double pendulum with the hard characteristic of elastic elements.

The article presents a generalization of the theory of long-term damageability to the case of discrete fibrous composites with orthotropic inclusions.

The theory of long-term damageability is generalized to the case of a discretely fibrous composite with stochastic structure. The appearance of damages in the composite is modeled by the formation of stochastically ...

The paper presents a technique for studying the natural frequencies of nonthin inhomogeneous shells of revolution acted by static axisymmetrical loads. The technique is based on a nonclassic shell model that takes all the ...

The performance characteristics of vertical-axis wind rotors with the control mechanism of blades are studied. The results of experimental researches in a hydrotray and a wind tunnel are given. The self-start of such wind ...

Edge effects near a mountain development of rectangular cross-section which is weakened by a thin crack are considered, by using numerical methods.

A mathematical model of the mechanics of thermoelastic bodies is proposed for the description of near-surface phenomena which are related to dissipative processes under the system transition from the equilibrium state to ...

An axisymmetric problem on the interaction of two parallel coaxial cracks of normal rupture in an infinite material with initial stresses acting along cracks is investigated with the use of approaches of the three-dimensional ...
