Abstract
A finite-element solution for a geometrically nonlinear fiber composite shallow shell with Stringer-type stiffeners is presented. A laminated, anisotropic thin/thick shallow stiffened shell finite element is developed and applied for the solution of several static problems. Geometrically, a nonlinear finite-element model is based on the nonlocking shear deformable theory. Stiffened composite cylinders are subjected to mechanical loading and the shallow shell theory is used for the geometric representation and formulation of the axially stiffened cylinders. A new, two-sided meshing system is generated to represent a cylindrical shell with stiffeners in a three-dimensional coordinate system.
