Skin Stringer Debonding Evolution in Stiffened Composite Panels under Compressive Load: A Novel Numerical Approach

Riccio, Aniello / Raimondo, A. / Scaramuzzino, F.

In this paper, a numerical study, on the compressive behaviour of stiffened composite panels with skin-stringer debonding has been carried out. The analysis has been performed by adopting a novel robust (mesh and time step independent) finite elements based numerical model on a single stiffener panel with an artificial debonding. In order to prove the effectiveness of the proposed numerical tool, the results in terms of debonded area growth and compressive load versus applied displacement, have been compared with experimental data available in literature.
