CHANGE OF THICKNESS OF WALLS OF CYLINDRICAL GLASSES AT AN EXTRACT WITHOUT CLIP
Kohun L.S., Morozov Y.A., Shul'gin A.V.
Abstract
He deformation model of thinning of sheet metal is considered at its turning in a spatial product. According to equality of the bending moments in the stretched and squeezed layers of preparation the size of neutral radius and the deformed values of external and internal radiuses is established are flexible, thickness of a material caused by change

MODELING OF NONLINEAR DEFORMATION AND BUCKLING OF ELASTIC INHOMOGENEITIES SHELLS
Bazhenov V.A., Solovei N.A., Krivenko O.P., Mishchenko O.A.
Abstract
He paper outlines the fundamentals of the method of solving static problems of geomet- rically nonlinear deformation, buckling, and postbuckling behavior of thin thermoelastic in- homogeneous shells with complex-shaped mid-surface, geometrical features throughout the thickness, and multilayer structure under complex thermomechanical loading. The method is based on the geometrically nonlinear equations of three-dimensional thermoelasticity and the moment finite-element scheme. The method is justified numerically. Comparing solutions with those obtained by other authors and by software LIRA and SCAD is conducted.

TREShchINY SO SVYaZYaMI V PERFORIROVANNOY STRINGERNOY PLASTINE
Mir-Salim-zade M.V.
Abstract
An unlimited perforated plate, reinforced by a regular system of ribs is considered. Plate weakened by a periodic system of surface cracks. The model of a crack with end zones in which crack surfaces interact is used. The boundary value problem for the equilibrium of the periodic system of cracks is reduced to a singular integral equation. The condition of the limit equilibrium cracks is formulated taking account to the criterion of the limit traction of bonds.

A METHOD OF COMPONENTWISE ANALYSIS OF STABILITY MARGINS FOR LARGE-SIZED SPATIAL STRUCTURES UNDER MULTIFACTORIAL LOADS
Men'shikov A.A., Gnezdilov V.A., Grigor'ev V.G., Kurnikov I.E.
Abstract
Покомпонентная оценка запасов устойчивости конструкции дает большее пони- мание о влиянии отдельных силовых факторов на сооружение в целом. Такой подход позволяет создавать более оптимальные и надежные конструкции. Методы, основан- ные на так называемом «параметре нагрузки», не могут правильно охарактеризовать ситуацию, когда конструкция нагружена совокупностью разнообразных внешних сил, по-разному влияющих на тенденцию потери устойчивости ее напряженно- деформи- рованного состояния. Для создания методики покомпонентного анализа крупногаба- ритных пространственных конструкций был применен подход, основанный на динами- ческой устойчивости, в котором для определения критической нагрузки рассматрива- ется задача о собственных малых колебаниях предварительно нагруженной конструк- ции. При таком подходе величина статической критической нагрузки соответствует ситуации, когда низшая собственная частота нагруженной конструкции приближа- ется к нулевому значению. Выполнены исследования различных ситуаций многокомпонентного нагружения на примере простой конструкций типа высотной башни, подкреплённой тросами, и сложных крупногабаритных пространственных ферменных сооружений, требующих нелинейного расчета. Выявленные эффекты потери устойчивости в сложных конструкциях подтверждают актуальность предложенной методики и перспективность ее применения при проектировании сооружений.
