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，用于评估承受实际载荷条件的结构的疲劳寿命。这种新的方法是基于最新进展的实验技术，使之成为可能，第一次，调查的裂纹打开/关闭机制和裂纹驱动力的大量的疲劳周期（> 100万）的变幅，代表现实世界的应用。该项目将扩大澳大利亚在结构寿命预测方面的知识基础和研究能力。它将提高国内产品和行业的竞争力，促进澳大利亚在这一具有重要战略意义的研究领域的国际合作和领导地位。
