Abstract
The crack arrest capabilities and the load bearing characteristic of a stiffened and unstiffened panel subjected to uniform remote displacement field is examined in this paper. A four stringer stiffened wide panel is analyzed for a center crack, propagating towards the adjacent stringers. The linear elastic analyses indicated a decrease in stress intensity factor when the crack approaches the stiffener. The non-linear analysis with crack across the skin-stringer assembly indicated a reduction in strength relative to an unstiffened panel.
