Interaction between buckling modes of imperfect cylindrical composite shells
- S.P. Timoshenko Inst. of Mechanics, Kiev (Ukraine)
The problem of the postbuckling behavior and sensitivity to initial geometrical imperfections of multilayered composite cylindrical shells is solved with allowance for the interaction of different buckling modes. The solution is based on the Byskov-Hutchinson asymptotic method and nonlinear equations of a Timoshenko-type shell theory. Boroaluminum, boron fiber-reinforced plastic, and glass fiber-reinforced plastic shells with imperfections in the form of five superimposed modes of similar structure and geometry are investigated. Snapping loads with and without the interaction of buckling modes are calculated and compared. The evolution of the mode amplitudes in the prebuckling and postbuckling states and their ratio at the limit point is demonstrated. 13 refs., 3 figs., 1 tab.
