Damage propagation in composite structural elements — analysis and experiments on structures

Abstract

An overview is given of experiments and analyses, being performed at the structures level within the GARTEUR (Group of Aeronautical Research in EURope) Action Group AG16: ‘Damage propagation in composite structural elements’.Experiments have been carried out on sandwich structure, stiffened flat and curved panels and stiffened cylinders, and on derivative simplified specimens.The specimens were provided with impact damage or artificial defects. New test methods are being developed and detailed measurements are being carried out to determine damage growth and failure mechanisms. The work should result in design guidelines and analysis methods applicable to the type of structures that have been investigated.
