摘　　要：用有限元方法对复合悬臂曲梁进行了数值分析,求得了复合悬臂曲梁的正应力和切应力。设计并制作了复合悬臂曲梁的实验模型并进行了应力测试,将两者结果与解析解进行比较,进一步验证了复合曲梁的理论公式的正确性,此举也为高校有关复合曲梁的开放性实验提供了一些参考。This paper analyzed the stress and strain in composite cantilever curved beams by means of finite element method. The models of testing of the composite cantilever curved beams were designed and fabricated for measuring the stress and strain. The both results were compared with that of the analytical solutions, and the analytical solutions were verified. This work provides the reference for the composite curved beam testing.
