Development of a new approach to solving the problem of nonlinear deformation and stability of cylindrical composite shells in the presence of initial imperfections on the surface of the shells in the form of dimple. Creation of a method for calculating critical loads and deformation trajectories. Investigation of the destruction of composite material during compression along a near-surface disc-shaped crack in half-space. It is planned to study the dependence of boundary effects and the stability of laminated and fibrous composites on the joint effect of their structural inhomogeneity, the anisotropy of components and loading conditions, and the behavior of critical parameters of the destruction of composite material for small distances between a crack and a free surface. popup.nrat_date 2024-12-10 Close
