Abstract :

Standard test methods to determine delamination resistance impose significant constraints on the specimen geometry and stacking sequence, thus they do not enable direct evaluation of the fracture toughness in many configurations of real-life practical interest (such as non-flat geometries, non-midplane delamination, [a/b] interfaces). In this talk, some alternative testing configurations are introduced and explored, enabling us to tackle these difficulties and achieve information on more general (co-cured or bonded) interfaces. The advantages and drawbacks of the different testing configurations are discussed, as well as the mechanical significance of the measured interface characteristics with respect to the classical testing methods.

Bio:

Federica Daghia is Adjunct Professor (Maître de Conférences HDR) at the École Normale Supérieure Paris-Saclay. She is secretary of the French Society for Composite Materials, as well as member of the French National Committee for Scientific Research, Division 9 (Mechanics of Solids, Materials and Structures, Biomechanics, Acoustics). Her research interest revolve around the modeling, experimental characterization and simulation of the behaviour until failure of architectured materials, including polymer matrix composites.
