Abstract
In this paper, a unified ethod is presented to model delaminated stiffened laminated composite shells, for synthesizing accurate multiple post-buckling solution paths under comprssive loading, and for predicting delamination growth in an a posteriori sense with reference to finite element applications. A multi-domain modeling technique is presented for modeling the delaminated stiffened shell structures. Error-free formulations axe presented for a 2-noded curved stiffener element and a 3-noded shell element for geometrically nonlinear applications. An accurate and simple automated solution strategy based on Newton type iterations is presented for predicting the general geometrically nonlinear and postbuckling behaviour of structures. Finally, a simple method is derived for predicting the delamination growth in terms of pointwise energy release rate at the delamination front from the 3-dimensional J-integral.
