dc.description.abstract |
The thin-walled spherical cap loaded by an external pressure generally performs a nonlinear
behavior. This phenomenon is not as significant in case of the hinged cap with restricted
movements in the radial direction. The linear analysis of the critical load shows that stability of the
cylindrical cap is practically identical to stability of the cylindrical shell. In addition, the non-linear
analysis further leads to the conclusion that the ratio between critical pressure and limit pressure
might be expressed by formula pCR/pLE=1.6. Based on these facts, the limit elastic pressure pLE of
an ideal cap can be derived from a critical external pressure pCRA of the spherical shell
pLEpCR/1.6pCRA/1.6. Conversion of pLE to the limit pressure of a real spherical cap in elastic-plastic
area pu might be performed by means of the procedure provided by ECCS [3]. The influence of
initial imperfections on stability of the spherical cap is a subject of further research. |
