Keywords: bonded joints, stiffened panels, post-buckling

Today's high-strength and damage tolerant materials allow for significant increases in working- and limit stresses in aircraft structures. The present work is concerned with the stress analysis of adhesively bonded skin-to-stiffener joints in post-buckling. To this end, a fully non-linear finite element global-local approach was used.
