- Abstract
- On the basis of the model of broken line the investigation of the critical parameters of the triply-layer spherical shells from composite materials at stability loss from action of the exterior pressure are investigated. By means of asymptotic analysis the simple calculated formulae are derived. They are good compatible with exact solution. The principal patterns of the shells behavior which are under expertise depending on generalized constructive parameters are investigated. The criterions of the mathematical models applicability more low level - direct line and fixed normal are stated. The results are generalized on the multi-layers spherical shells.
