The cohesive element (CE) has been widely used to model delamination in laminated
composites. The penalty stiffness, interfacial strength and fracture toughness are three CE …

Thin-walled composite structures operating in the post-buckling regime needs a thorough
understanding of their stability behavior and failure mechanisms. For the accurate prediction …

Two aeronautical thermoplastic composite stiffened panels are analysed and tested to
investigate the buckling behaviour, the skin-stringer separation and the final failure mode …

Thermoplastic composite three-stringer panels with omega stiffeners and conduction welded
joints are designed, analysed and tested until final failure to investigate the performance of …

Despite the increased applications of the composite materials in aerospace due to their
exceptional physical and mechanical properties, the machining of composites remains a …

Cohesive zone models and criteria based on finite fracture mechanics are two alternatives to
analyze edge debonding. A comparison between the two approaches is presented in this …

The postbuckling response and failure of multi-stringer panels is analyzed using finite
element models with three levels of approximation. The first model is based on a relatively …

With the growing demand for composite parts, more and more designs or re-designs are
required to use such materials. This paper presents a new methodology for designing …

This study concerns a computational model for the postbuckling failure mechanism of
composite T-stiffened panels with different bonding methods. The model is then validated …
