CALCULATION OF THE INTENSE DEFORMED STATE OF TANK’SWALL UNDER THE ACTION OF THE HYDROSTATIC LOAD IN ANONLINEAR SETTING WITH GEOMETRIC IMPERFECTIONS
The work substantiates the necessity of taking into account the specificity of the hydrostatic load when calculating the wall of a tank with geometric imperfections. A stepbystep scheme for loading the tank wall with hydrostatic pressure has been developed, which makes it possible to perform a geometrically nonlinear elastic analysis with imperfections included geometry. The intense deformed state of an exploited tank with geometric imperfections under the action of a hydrostatic load was studied, which made it possible to reveal the tendency of the stress change as the tank was filled. The carried out research allows determining the maximum height of filling liquid in the deformed reservoir for its further safe operation.
