Non-linear bending and stability of the clamped prolate semi-ellipsoidal domes with different wall thickness under uniform external pressure and temperature change are considered. The whole analysis is performed numerically using combination of the successive approximation method, linearization and orthogonal sweep methods. Unsymmetrical critical pressure is examined at cryogenic and elevated temperatures taking into account dependence of material characteristics on the temperature. The bifurcation loads with number of circumferential waves are determined. We find that the non-axisymmetrical critical loads for all considered domes are larger at cryogenic temperatures and decrease at higher temperatures. [ABSTRACT FROM AUTHOR] |
