Double-grid curvilinear elements that describe three-dimensional stress state of homogeneous and composite cylindrical shells and panels of variable thickness are offered, their attaching and loading complex nature is taken into account. Double-grid elements take into account the heterogeneous structure of panels and shells and give raise to discrete models of small dimension.
