  • Crack Penetration and Deflection Behavior at Interfaces

    Creator:
    Alam, Mahabub
    Abstract:
    This study computationally and experimentally examines the mechanisms of crack penetration, deflection and the transition between penetration and deflection. The finite element analysis based computational modeling work used strength-and-energy based cohesive-zone approach to study the effect of dimensionless parameters (e.g., interfacial incident angle, fracture-length scale, and normalized toughness) on penetration/deflection...

  • Investigation into the role of strength and toughness in composite materials with an angled incident crack

    Creator:
    Grimm, Brian A.
    Abstract:
    Understanding the mechanical behavior of composite materials requires extensive knowledge of fracture behavior as a crack approaches an interface between the bulk material and the reinforcement structure. Overall material toughness can be greatly influenced by the propensity of an impinging crack to propagate directly through the substrate or deflect along...
