摘要
The delamination near the centre crack of ARALL under fatigue and static loads is investigated, and the effects on delamination by 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 presents symmetrical hi-ellipse-shape, whereas under the condition of static tensile, the edge-effect becomes more evident. Applying a proper pre-stress to the laminate can increase the ability of anti-delamination damage.
