Abstrakt: The numerical analysis of the processes of elastic-plastic deformation and limit states of shell structures of large-size tankers filled with loose goods upon bending in the course of unloading is conducted. The solution of a three-dimensional geometrically and physically nonlinear problem is based on the finite element method and explicit scheme of integration in time of the 'cross' type. A critical load at which the tanker losses its stability is defined. The influence of the load, internal pressure, and length of the tanker on stability is studied. [ABSTRACT FROM AUTHOR]
