Abstract: The delamination near the centre crack of ARALL under fatigue load and static load is investigated, and the effects on delamination of different residual stresses are analyzed. The results show that the situations under the two kinds of loads are different. Under the fatigue load, the typical delamination with crack growth is symmetrical bi\|ellipse. But under the condition of static tensile, the edge\|effects become more evident. Applying a proper pre\|stress to the laminate can increase the ability of anti\|delamination damage.
