abstract: "<p>Ply-block size and stress level effect on accumulation of transverse cracks and delamination are investigated during early fatigue life of CFRP laminates. Tension-tension fatigue tests under different stress levels were performed for two cross-ply configurations. Edge observation with digital cameras, digital image correlation and acoustic emission were employed for in-situ damage monitoring. Transverse cracks were dominant for [0/90<sub>2</sub>]<sub>s</sub> laminates with almost non-existent delamination, while different interactive levels between both damage mechanisms occurred for [0<sub>2</sub>/90<sub>4</sub>]<sub>s</sub> laminates. Poisson’s ratio identifies whether early fatigue damage is dominant by transverse cracks or involves delamination. Cumulative AE energy is a helpful indicator of crack density.</p>"
