A Study on Geometrically Nonlinear Analysis and Critical Shear Stress of Short Cylindrical Shells |
| Abstract |
The elastic failures of cantilevered cylindrical shells under the transverse load are mainly caused by the geometrical nonlinearity. The modes of their failures are largely determined by the shapes of the shell. Because the cantilevered cylindrical shells under the transverse load have unsymmetrical deformations to fail, the geometrically nonlinear analysis is needed to closely evaluate the critical point. The short cantilevered cylindrical shells under the transverse shear load at its tip have the phenomenon of elastic shear buckling. The evaluation of the critical shear stress is needed to design for the short cylindrical shells.In this paper the geometically nonlinear analysis of cantilevered cylindrical shells by the Rayleigh-Ritz Method is presented to examine the critical point and the critical shear stress. The critical shear stresses are compared with the stresses using eigenvalue and experimental data, and the critical stress of torsional buckling stress which are from the references. |
