Transformable calculation schemes in geometrically nonlinear problems of mechanics of sandwich plates with the contour reinforcing beams

Abstract

© 2019 IOP Publishing Ltd. The transformable calculation schemes for geometrically nonlinear problems of mechanics of sandwich plates with contour reinforcing beams are constructed. To solve the boundary value problem, it was used by the finite sum method. The solving the nonlinear problem arising in this case using a two-layer iterative process with the lowering of nonlinearity on the lower layer was carried out. A software package implemented in the Matlab environment has been developed. Numerical experiments were carried out and their results were analyzed
