INFLUENCE OF PHYSICAL NONLINEARITY ON THE CALCULATED INDICATORS OF STABILITY OF RETICULATED ONE-SHEET HYPERBOLOID OF REVOLUTION WITH DIFFERENT FORMS OF GENERATRICES

Cover Page

Abstract


The article contains a comparative stability analysis of initial equilibrium forms of reticulated one-sheet hyperboloids of revolution. The calculations are performed taking into account the geometric and the dual (geometric and material) nonlinearities. The influence of the shape of generatrix one-sheet hyperboloid of rotation on shells stability in these formulations of the problem is considered. The equilibrium curves of shells with load acting on the upper base are shown.
