Modelling the Mechanical Behaviour of Steels under High Loading Rates
Abstract:

The advent of steel in the construction of engineering structures used in both offshore and onshore environments by different sectors has over decades experienced huge acceptance compared with other materials. Its acceptance has made material scientist and engineer commit more research work into improving its microstructural and chemical compositions in order to improve its structural reliability. Various researches have gone into improving the metallurgy of steel ranging from low, medium and high strength steel material used for different purposes. However, limited information exists for most of the modern high strength structural steels and consequently high yield tensile ratio used in offshore applications. The acceptance of modern high strength steel is limited in design codes and more restrictive for tubular offshore applications because of the fear and argument by designers and engineers that the safety margin provided by lower strength steel is being eroded. The benefits of High Strength Steel (HSS) and the improved combination of mechanical properties (strength, toughness and weldability) it offered have been under-utilized for offshore applications. Therefore there is the need to develop a dataset and have a broad understanding on the behaviour of these HSS with high yield ratio subjected to different loading conditions and taking into account the extreme cases of strain rates.
