Abstract

This study aims to predict the transverse crack accumulation behavior of CFRP cross-ply laminates for evaluation of their remaining life. The tension-tension fatigue tests of CFRP cross-ply laminates were used to investigate the relationship between transverse crack accumulation behavior and the number of cycles of the fatigue tests. We also studied the damage accumulation behavior, including delamination of cross-ply laminates under fatigue loading, and it was indicated that the damage accumulation behavior depends on the maximum load of the fatigue tests. We proposed a method that can predict transverse crack accumulation behavior using a power-law between transverse crack density growth rate and the energy release rate associated with single transverse crack formation. As a result, the proposed method can estimate the applied number of cycles on CFRP cross-ply laminates.

CFRP层板在拉张疲劳载荷作用下横向裂纹扩展的预测

本研究旨在预测CFRP交叉层板的横向裂纹累积行为，以评估其剩余寿命。利用碳纤维布层板的拉伸-拉伸疲劳试验，研究了横向裂纹累积行为与疲劳试验循环次数之间的关系。我们还研究了疲劳载荷下的损伤累积行为，包括交叉层压板的分层，结果表明，损伤累积行为取决于疲劳试验的最大载荷。我们提出了一种方法，可以使用横向裂纹密度增长率和与单个横向裂纹形成相关的能量释放率之间的幂律来预测横向裂纹累积行为。因此，所提出的方法可以估计CFRP交叉层板的应用循环次数。
