Abstract A semi-analytical model for buckling analysis of stiffened composite panel with debonding defect, subjected to in-plane shear load is developed and verified. The model formulation is based on the Rayleigh–Ritz method combined with the principle of total stationary potential energy. The domain is discretized ensuring the continuity , each domain displacement was approximated using a base of polynomial hierarchical functions. Finite element analyses and experimental tests were also performed to verify the proposed model and investigate the influence of the defect size on the panel stability. The proposed semi-analytical model is an efficient and accurate design tool that can be used in the prediction and identification of critical design scenarios for damage tolerant aerostructures.

Highlights A semi-analytical model for composite shear webs including skin-stiffener debonding defects is proposed. Buckling analyses of composite shear webs with different debonding defects are considered. The present modeling methodology handles arbitrary boundary conditions. The multi-domain partitioning strategy allows the inclusion of geometric discontinuities in a straight forward way.
