Determination of parameters for the damage mechanics approach to ductile fracture based on a single fracture mechanics test

The local approach to modelling ductile tearing is a useful technique to give insight into fracture mechanics. However, applications of the local approach have been stymied by the high cost of finding the parameters that characterize it because of the number of specimens and expensive post-processing that the testing requires. In this paper, a...

Failure and fatigue life assessment of steel railway bridges with brittle material

Some existing steel bridges have been constructed from steels with a toughness that does not fulfil the requirements in modern standards. In such a case, standards for bridges do not provide an alternative assessment route. Yet such bridges may still be fit for purpose. This paper presents an assessment method for structural safety and for the...
