The Comparative Analysis of Calculation of Durability and Stability of the Supported Shells on the Basis of the PC OBOLOCHKA and PC ANSYS

Authors: Baranova D. А., Volynin А. L., Karpov V. V.

To substantiate the efficiency of the PC OBOLOCHKA use for research of durability and stability of the supported shells the article compares the received results of calculation with the results found through PC ANSYS use.

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 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.
