| dc.description | The strength of a thin-walled cylindrical tank was evaluated under the combined action of the hydrostatic pressure of the liquid and the additional gas pressure. To determine the stresses in the dangerous intersection near the flat bottom of the tank, the presence of boundary forces is taken into account. The dependences for determining the boundary forces were obtained by solving the equation of deformations compatibility of a thin-walled cylindrical shell and a round plate resting on a solid surface. It was found that the meridian stresses in the tank wall at the junction with the round bottom plate are 3.6 times greater than the values of such stresses, determined by the momentless theory of shells. Therefore, taking into account additional gas pressure and boundary forces to calculate the strength of a cylindrical tank with a flat bottom increases the values of stresses and changes the correlations between them. Such factors of impact on the strength must be taken into account both during the design and during the use of the tanks. | en_US |
| dc.description.abstract | The strength of a thin-walled cylindrical large-capacity tank was evaluated. The walls of the tank and the bottom are simultaneously exposed to hydrostatic pressure of the liquid and additionally gas pressure-loaded. The stress at the bottom of the tank was determined taking into account the boundary forces under the combined action of hydraulic and gas pressures. The dependences for determining the boundary forces were obtained by solving the equation of deformations compatibility of a thin-walled cylindrical shell and a round plate resting on a solid surface. The influence of gas pressure increase on the magnitude of stresses was investigated. | en_US |
