Effect of Loading Parameters on Fatigue of Composite Laminates: Part V

摘要

This report is the fifth in a series of reports on the damage growth of notchedand visible impact-damaged AS4/3501-6 graphite/epoxy quasi-isotropic laminates under long-term mechanical fatigue loading. The effects of load type, load level, load sequence, and spectrum modification are evaluated in this study. X-ray radiography is taken of the test specimens to monitor the fatigue damage, which are in the form of splitting and delamination around the center hold of a specimen.
