摘　　要：本文研究了胶粘剂、胶粘剂含量及不同残余应力状态对含缺口ＡＲＡＬＬ层板的分层损伤的影响，并试图采用特征长度理论来描述不同缺口层板的分层状态。结果表明，运用源于密集能量区概念的特征长度理论可以定性地分析或半定量地描述ＡＲＡＬＬ缺口层板的分层损伤。The effect of type and amount of adhesive used and residual stress on the delamination damage of center-notched ARALL was investigated. The character istic-length theory was tried to be adopt to describe the state of delamination of the laminated board with two kinds of notches.The results shows that the theory of characteristic-length from the concept of concentrating energy region can be applied to analyse qualitatively or to describe half-quatitatively the delamination of ARALL with notch.
