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

The article contains a comparative stability analysis of initial equilibrium forms of reticulated Apron 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 Ball - Bat - Wood base are shown.
