title = "Determination of the appropriate fracture mechanism for tensile armour wires using micromechanical model-based fracture mechanics",
abstract = "Flexible pipes are used for risers and flowlines in the offshore industry and in other applications. During flexible pipe construction, tensile armour wires are incorporated to resist longitudinal stresses which arise during installation and in service. Recent research on predicting the fracture behaviour of wires has employed a classical fracture mechanics approach. However, non-standardised fracture mechanics specimens were used as standard test specimens could not be manufactured from the wire owing to their size. Micromechanical-based fracture mechanics models serve as alternatives to classical fracture mechanics when standard fracture mechanics specimens cannot be obtained and when a safe use of the fracture mechanics concepts cannot be insured. Laboratory tensile testing and tensile testing finite element simulations with micromechanical-based fracture mechanics models carried out in this work reveal that the shear damage and fracture model provide an appropriate description of the fracture mechanism for tensile armour wires.
