Reliability Assessment of Light Weight Components

Dear Colleagues,

The main challenge in the transportation industry in achieving weight reduction and an increase of passenger safety which can be directly addressed by the development of multi-material load-bearing components and structures with improved performance for structural integrity and durability. Innovative structural designs can be implemented using advanced materials, as well as efficient joining and manufacturing concepts. An assessment of the structural integrity of components and structures is a key for achieving the industrial maturity of the exploited materials and innovative manufacturing technologies. At that time, the assessment of structural integrity is of paramount importance to ensure safety for any engineering industry.

Further gains in structural performance can be achieved through the application of local modification technologies. This can be done by either imposing residual stress fields or strengthening elements, which mitigate crack initiation and/or growth. For example, in aircraft components and engines, emphasis has to be placed by developing strategies for life extension of ageing aircrafts in order to ensure structural safety beyond design lifetime.

Meeting the challenges in structural integrity is the focus of research articles within the Special Issue “Reliability Assessment of Light-Weight Components”. The issue aims at a broad coverage of structural integrity issues, including material characterization from the fatigue and fracture point of view, numerical modelling of those phenomena in materials and structural applications, failure analysis methodologies and structural integrity evaluation criteria. Topics of research articles can include, but are not limited to:

• reliability and integrity of metallic components and structures
• structural integrity issues for welded and additive manufactured components and structures
• probabilistic approaches to damage tolerance assessment
• fatigue life prediction methodologies for metallic components and structures
• surface engineering approaches and failure resistance improvement
• durability and life extension of metallic components and structures
• residual stress engineering for damage tolerance improvement and life extension
• life extension and repair of metallic components and structures
• advanced testing and evaluation techniques
• advances in fracture mechanical analysis
