Abstract
Experimental and numerical investigations of adhesively stiffened composite panels were performed to discuss the load-carrying capacity of different design at stiffener run-out. The compression experiment revealed that the failure was initiated at the edge of the run-out and propagated across the skin-stiffener interface. A fracture mechanical approach to utilize cohesive finite element was adopted in the numerical analysis of these specimens. It was shown that the finite element analysis using solid element and cohesive element was able to qualitatively predict the crack growth characteristics for each specimen
