This PhD project aims to formulate and validate, through a systematic experimental investigation, a novel numerical methodology suitable for designing against multiaxial fatigue aluminium-to-steel hybrid welded joints manufactured using both primary and recycled aluminium. Owing to the fact that the multiaxial fatigue behaviour of aluminium-to-steel welded connections has never been investigated systematically before, via this PhD project for the first time specific methods suitable for designing such innovative joints would be developed. To maximise the impact of the outcomes of the present research work, the generated experimental results, the formalised design methods, and the technological innovation will be submitted to the International Institute of Welding (IIW, www.iiw.org) to be incorporated in the IIW Recommendations.

这个博士项目的目的是制定和验证，通过系统的实验研究，一种新的数值方法，适用于设计对多轴疲劳铝-钢混合焊接接头使用原铝和再生铝制造。由于铝-钢焊接接头的多轴疲劳性能以前从未被系统地研究过，因此通过这个博士项目，将首次开发出适用于设计这种创新接头的具体方法。为了最大限度地发挥目前研究工作成果的影响，所产生的实验结果，正式的设计方法和技术创新将提交给国际焊接学会（IIW，www.iiw.org），以纳入IIW建议书。
