Most fatigue studies carried out to date have been based on uniaxial loading of the tested structure. The limited work that has been carried out on a multiaxial fatigue behaviour indicates that the uniaxial fatigue results can be conservative by a factor of up to twenty. In order to maximise the amount of weight reduction, which can be achieved by down-gauging steel for future automotive applications, it is necessary to evaluate automotive components, laser welded blanks and bonded blanks under multiaxial load conditions. The results generated will be used to develop a general model in order to predict the likely performance of different steel types and joining methods under multiaxial fatigue conditions to enable the optimisation of designs for high strength steels in light weight automotive construction. Both uncoated and zinc coated steels will be used in this study.
