The short beam shear performance of GLARE 3A-3/2 laminates with adhesive layers was investigated by combining the short beam test and the digital image correlation technique. The failure behavior was further analyzed based on finite element simulation and micro failure morphology. The results show an 8% and 58% difference in the short beam strength and bending displacement at failure of laminates along two orthogonal directions; The damage behavior of laminates is determined by the bottom unidirectional glass fiber reinforced plastic (GFRP) layers. The two typical failure modes are matrix and fiber fracture in the GFRP layer caused by local bending deformation, and interlaminar delamination between GFRP layers; The distribution of surface strain ${\epsilon }_y$ indicates the damage initiation and evolution process. The simulation result of the finite element model established in ABAQUS/Explicit shows consistency with digital image correlation analysis, which provides an effective method to predict the damage behavior of specimens with different ply structures.

通过结合短梁测试和数字图像相关技术，研究了具有粘合剂层的 GLARE 3A-3/2 层压板的短梁剪切性能。基于有限元模拟和微观失效形态进一步分析失效行为。结果表明，沿两个正交方向的层压板失效时的短梁强度和弯曲位移有 8% 和 58% 的差异；层压板的损坏行为由底部单向玻璃纤维增​​强塑料 (GFRP) 层决定。两种典型的破坏模式是局部弯曲变形引起的GFRP层内基体和纤维断裂，以及GFRP层间的层间分层；表面应变分布${\epsilon }_{是}$表示损伤的发生和演变过程。在ABAQUS/Explicit中建立的有限元模型仿真结果与数字图像相关分析一致，为预测不同层板结构试件的损伤行为提供了一种有效的方法。
