A finite-element model is developed based on progressive failure analysis (PFA). The proposed model shows ability to predict correctly the final strength and simulate main damage modes involved in post buckled CFRP stiffened panel under compression.

Variable stiffness composite cylinders with circular and elliptical cross-sections made by fiber steering are designed and optimized for maximum torsion-induced buckling capacity. A metamodeling based design optimization method is used for this work.

Adhesively bonded composite joint configurations with different mechanical fasteners were investigate both experimentally and numerically to identify and quantify mechanisms that arrest crack growth in the adhesive bondline when loaded in fatigue.

Interlocked continuous fibers introduced in adhesive layer bridged crack and suppressed its propagation. Mode II fracture toughness tripled compared to specimen without arrester. New manufacturing method for robust arresting was also demonstrated.

This paper explores a first-pass progressive damage model for a 3D woven aerospace composite single-bolt, double-shear joint. A mesoscale approach was adopted to separately consider the failure response of impregnated tows from surrounding matrix.

The influence of the specimen width in the procedures to obtain cohesive laws by J-integral method using an advanced analytical DCB model with a coupled cohesive damage is studied and a new correction function has been proposed.

The in-plane and out-of-plane mechanical behaviour of ultrasonically spot-welded and mechanically fastened joints are characterized through double-lap shear and pull-through tests. Fractography is used to investigate the failure mechanisms of joints.
