Yakimkin O. Numerical analysis for deformation of the three-ply construction's elements considering exfoliation evolution

Dissertation is dedicated to numerical analysis for deformation of the three-ply construction's elements with exfoliation. Calculation model for determining non-linear deformation of such complex elements with considering exfoliation evolution was built. High effective algorithm for stability exploring of the three-ply laminas and shells was developed and adapted to consider one-side contact between adjacent plies. Set of new tasks, dedicated to non-linear deformation and stability of the three-ply laminas and shells, was resolved. Additionally, dependence of critical parameters and rigidity loss of the fore mentioned objects from different types of exfoliation evolution and one-side contact between plies was revealed.
