The generation of deformation damage during fatigue loading in Al-Cu alloy studied by the Doppler Broadening technique

We have investigated the evolution of damage during fatigue loading in Al–Cu 2024-T3 alloys using the positron annihilation Doppler Broadening (DB) technique. This technique enables us to monitor in a non destructive way, at the atomic and vacancy level, the formation of deformation defects and their interaction with solute atoms at selected...

Fatigue properties of AA2024 for intermittent thermal healing and analysis of damage development using positron annihilation Doppler broadening technique (abstract)

Lamb wave detection in prepreg composite materials with fibre Bragg grating sensors

This paper demonstrates that existing Structural Health Monitoring (SHM) techniques have potential during the production phase in addition to their application for maintenance and for in-flight monitoring. Flaws occur during composite fabrication in industry, due to an imperfect process control and human errors. This decreases production...

Understanding the Fatigue Behavior of FML Structures and Materials under Complex Variable Amplitude Loading

This paper presents various failure mechanisms in FMLs, highlights the presence or absence of interaction effects, and describes how the failure mechanisms can be described for predicting damage growth under arbitrary complex load spectra.
