Stability of conical shells of an elliptical cross-section

The study deals with sectional conical shells of an elliptical cross-section with rigidly fastened edges. The work is aimed at studying into stability of rigidly fastened sectioned conical shells of an elliptical cross-section with a large eccentricity under the action of a uniform external pressure, axial compression and a torque moment applied to the shell ends. Structural formulae of critical loads of elliptical sectioned cones under the action of axial compression, external pressure or torque have been derived. The behaviour of sectioned elliptical cones under the action of axial compression, external pressure or torque is described; formulae for estimation of critical loads of local and general loss of stability by elliptical cones under axial compression, external pressure and torque are derived; a technique of manufacturing models of thin-walled sectioned conical shells with parallel bases and rigidly fastened edged is developedAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
