Abstract

The initiation and growth of fatigue damage in notched Cycom AS4/1808 graphite/epoxy laminates were investigated experimentally. Two layups, (0/45/90/-45)s4 and (0/45/0/-45)s4, provided contrasting responses to the fully reversed fatigue loads. Full-field strains and stresses surrounding the circular notch were evaluated at several stages of fatigue life with the photoelastic coating and adiabatic thermal emission measurement techniques and were related to the corresponding damage state and residual strength, stiffness, and life.
