Abstract: Possibility of active use projective-iterative schemes of variation-mesh finite element method for calculation of the launch vehicles compartments is discussed. It is important in the design and development of newly produced launch vehicles, when the big volume of different calculations is necessary. The problems of strength for the cylindrical compartments with cutouts at inelastic deformation of material are developed.
