Numerical solution of nonlinear problems of stability of cylindrical isotropic shells based on dynamic criteria

Abstract

Numerical solution of nonlinear problems of stability of cylindrical isotropic shells based on dynamic criteria

S.I. Timofeev

In the framework of the nonlinear buckling considered the problem of determining the critical pressure, distributed over the face of the cylindrical shell. Buckling criterion is the appearance of positive acceleration directed along the normal to the middle surface of the shell. Numerical solution of the system implemented in MathCAD. Given its comparative analysis with the known solution formula Papkovich. 
Keywords: cylindrical shell, nonlinear stability, numerical solution, the system MathCAD.
