| Popis: | The fracture behavior of welded single edge notched tension specimens was examined using constraints and loading conditions which approximated those of a flawed ship structural panel. The specimens were notched and fatigue pre-cracked in the microstructural region associated with a brittle coarse grained heat affected zone and dynamically fractured at the minimum design temperature. In all cases, the fracture event was preceded by some degree of plasticity. With the aid of validated finite element method companion models, a crack mouth to crack tip opening displacement transfer function was generated allowing the fracture toughness at failure to be determined. |
