internally developed research programmes to correlate instrumented Charpy testing with Pellini test results and crack arrest data for high strength weldable ship structural steels.
Collaborative industry research project to develop an Acoustic Emission based fracture initiation and propagation and measurement tool.
There are many Lloyd’s Register internally developed research programmes. Some of particular interest include fatigue of welded ship structures, with particular reference to the effects of :
- Surface treatment on welded connections.
- Low cycle loading which exceeds the yield point.
Variable amplitude loading including compression.
