Abstract

The results of the experimental analysis of tanks models are considered. The cylindrical panels are used for the tank models. Such structures with imperfections describe the deflected mode of big cylindrical tanks with imperfections. The results of the experimental investigations of the deflected mode in the region of imperfections are presented. The results are obtained by tensometric approach. The stress concentration factors in the regions of imperfections are analyzed in details. The deflected mode of the cylindrical tank with spherical imperfections is simulated numerically. It is assumed that the tank material meets the Hooke law and deformations and displacements satisfy the linear equations. As the tank is filled by fuel oil, then the constant internal pressure acts on the internal surface. The finite element method is applied to simulate numerically the deflected mode. The dependence of the stress concentration factors on the dimensionless parameters of imperfections is analyzed.
