Investigation of Buckling Behavior for Thin-Walled Bearing Aircraft Structural Elements with Cutouts by Means of Numerical Simulation

Resumo

In this paper, we develop the consistent mathematical models and appropriate lowconsuming numerical methods for investigating the nonlinear strain and buckling behavior of statically loaded thin-walled structures with cutouts. The numerical simulation allowed us to study the effects of the dimensions of rectangular cutouts on the buckling of cylindrical shells loaded by the external pressure.
