ON DIFFERENT SHELL MODELING IN NUMERICAL ANALYSES OF A COMPOSITE STIFFENED PANEL UNDER UNIFORM PRESSURE

ON DIFFERENT SHELL MODELING IN NUMERICAL ANALYSES OF A COMPOSITE STIFFENED PANEL UNDER UNIFORM PRESSURE

Reinoso, J.; Blázquez, A.; París, F.; Irslinger, J.; Ramm, E.

Full Article:

This work deals with the evaluation of the different modeling options based on the FEM to reproduce the structural performance of a composite stiffened panel in postbuckling regime under uniform pressure. Two fundamental modeling options are used for this purpose: monolithic and multi-part approaches. These strategies are based respectively on standard and 7-parameter finite element shell formulations as underlying mechanical theories. The numerical results obtained by means of these alternatives are compared with the experimental response of the panel with special emphasis in the postbuckling evolution of the behavior of the structure, and incorporating the initial geometric imperfections of the panel in the simulations.
