Mathematical Models of Stability Loss of Nonuniform Cylindrical Shells Because of Nonuniform Radial Loading

Authors: Antonenko N. N.

The circular cylindrical shell with variable thickness along the axis of elongation is considered. The axisymmetric radial pressure along the axis of shell is suggested. The one of values (for the law of pressure variation) which effects the stability loss of shell is determinated.

The Parametric Oscillations of Heterogeneous Round Cylindrical Shell of Variable Density on Different Boundary Conditions

Authors: Mochalin A. A.

We consider an isotropic cylindrical shell of varying thickness and density along the generatrix. Let the shell be under pressure, which is symmetric and also varying along the generatrix. We follow the polupostamenty theory by V. Z. Vlasov and consider the problem of the dynamical stability of the shell. We obtain the exact solution corresponding to the certain relation between thickness, pressure and density.

The stability of the constructive-orthotropic heterogeneous cylindrical shell under uneven radial load

Authors: Mochalin A. A.

On the base haft-momentum Vlasov theory the problem of stability of cylindrical homogeneas shell with variation of thicknees atv radial symmetrical ractial pressure variated onalong axe distance. At one reletion between thickness and pressure values the accurate solution was produced for one values in pressure variation law when stability of shell is sailed.
