Experimental and analytical study of fatigue damage in notched graphite/epoxy laminates [PDF]

open access: yes
Both tension and compression fatigue behaviors were investigated in four notched graphite/epoxy laminates. After fatigue loading, specimens were examined for damage type and location using visual inspection, light microscopy, scanning electron microscopy,
