| 摘 要： | 本文对不同芯材、不同高跨比的轻质复合材料夹层梁进行了试验研究.通过对夹层梁的各种破坏模式进行分析,研究了夹层梁的破坏模式与荷载、材料基本力学性能、几何参数的关系,并在此基础上绘制了夹层梁破坏模式图,预测了夹层梁的破坏模式.试验结果与理论分析吻合较好,夹层梁设计参数变化会引起破坏模式的相应改变.

| Abstract: | Several composite sandwich beam specimens with different core materials and different face-thickness-to-span ratios have been developed for the study of failure modes.The relationships among failure modes and loads,material properties and geometric parameters are examined.Failure maps are presented and the failure modes are predicted.The results show that a well agreement is obtained between the experimental results and theoretical analysis.The change of sandwich beam design parameters will cause correspond... |
