The Cut-and-Try Method in Determining the Saturate Spacing of Transverse Cracks of Composite Laminates

摘要: 本文首次通过三维有限元法计算分析出90°层中横向裂纹的饱和间距值,为预测饱和裂纹间距提供了一条新途径.

Abstract: In this Paper, the saturate spacing of transverse cracks of the 90°ply is originally calculated by the 3-D finite element method. Thus, a new approach is put forward for predicting the saturate spacing of transverse cracks.
- transverse crack /
- saturate crack spacing /
- damage /
- stress
