摘要: Abstract A comprehensive experimental program was conducted to measure and characterize the development of damage in vicinity fastener holes graphite/epoxy composite laminates. This carried out generate data which can be used for appropriate failure criteria. Test specimens were loaded quasi-static cycles with successively increasing loads, bolt detected using different methods such as strain measurements, acoustic emission, X-ray microscopic examination. Several modes a series events starting at load levels far below level first visible evidence appeared on load–displacement curve. Failure included matrix cracking, fibre fracture, delamination kinking.
