| Description |
The objective was to
develop a methodology to detect, evaluate, and to control local brittle zones (LBZ) in the
construction verification of offshore platforms. LBZ's are regions of brittle
microstructure within the heat-affected zones of steel weldments that can initiate brittle
fracture. They can also cause a fatigue failure to platforms subject to wind and wave
loadings. The major objective was to review the test methods that are currently used to
detect, assess, and control LBZ's and to make recommendations for new test methods for
fracture control. |
