The project will develop a new methodology for the assessment of fatigue life of structures subjected to realistic loading conditions. This new methodology is based on recent advances in experimental techniques which make possible, for the first time, the investigation of the crack opening/closure mechanisms and the crack driving force for large numbers of fatigue cycles (>1 million) of variable amplitude, representative of real-world applications. The project will expand Australia’s knowledge base and research capabilities in structural life prognosis. It will increase the competitiveness of domestic products and industries, fostering international collaborations and leadership of Australia in this strategically important area of research.

该项目将开发一种新的方法来评估结构在实际载荷条件下的疲劳寿命。这种新方法基于实验技术的最新进展，这使得首次研究具有代表性的实际应用的可变振幅的大量疲劳循环（bbb100万）的裂纹开/闭机制和裂纹驱动力成为可能。该项目将扩大澳大利亚在结构寿命预测方面的知识库和研究能力。它将提高国内产品和产业的竞争力，促进国际合作和澳大利亚在这一具有重要战略意义的研究领域的领导地位。
