Abstract

An energy based smeared stiffener model is developed to obtain equivalent stiffness coefficients of a general grid-stiffened composite cylindrical shell. These equivalent stiffness coefficients are used in the Ritz buckling analysis of the shell. Transverse shear properties are important in a stiffened shell and results are obtained for First order Shear Deformation Theory (FSDT) as well as for Classical Laminated Shell Theory (CLST). Parametric study is carried out to find out the effects of various design parameters on specific buckling load of the shell.
