Abstract
Manufacturing characteristics of the filament winding process, such as formation of the winding pattern, are usually not taken into account in conventional numerical models. This paper deals with the evaluation of the influence of the filament winding pattern on buckling behavior in cylindrical shells subjected to axial compression loads. A nonlinear buckling model was developed, the damage initiation criteria were based on the Hashin theory, implemented in finite element software Abaqus. The modeling of the cylinders took into account the effect of the winding pattern. The numerical results were compared with experimental results previously tested, where it was verified that the nonlinear model provides a satisfactory prediction of the displacements over the loading history and the critical buckling load.
