In this work, the stringer termination debonding on a tensile-loaded hybrid metallic-composite stiffened panel is numerically investigated. The analyzed structure consists of an omega-reinforced CFRP panel joined with a Z-reinforced aluminum plate. An initial debonding is considered between the composite skin and the omega stringers, and the delamination propagation is investigated as the applied load increases. Subsequently, additional sub-components are introduced to mitigate the delamination propagation. The numerical results are compared and critically discussed.

Abstract
In this work, the stringer termination debonding on a tensile-loaded hybrid metallic-composite stiffened panel is numerically investigated. The analyzed structure consists of an omega-reinforced CFRP panel joined with a Z-reinforced aluminum plate. An initial debonding is considered between the composite skin and the omega stringers, and the delamination propagation is investigated as the applied load increases. Subsequently, additional sub-components are introduced to mitigate the delamination propagation. The numerical results are compared and critically discussed.File in questo prodotto:
