Investigation on damage tolerance behaviour of aluminium allays (IDA)

Cel

Modern transport aircraft are designed for high efficiency and long service lives, resulting in heavy loaded structures. This application requires damage tolerant materials with low crack propagation rates. Recently improved alloys have been developed, enabling also new joining technologies like laser beam welding. These materials reveal a lack of understanding of the microstructure-crack growth relationship, existing for the well-known alloy 2024. This missing knowledge will be attained in this project by comprehensive material characterization to identify the complex fatigue and fracture relevant microstructure-crack growth relationship. Thorough fatigue crack propagation testing and complementary examination on crack surface morphology, plastic zone and crack closure effects will be performed. Based on the attained knowledge prediction models will be established and verified. Recommendations for optimisation of microstructures will be derived. This specific information will allow optimised application of the recently developed damage tolerant materials and laser beam welding technology, consequently improving Aircraft Efficiency
