Analytical failure prediction and fxpcrimental evaluation of baltcd connections in composite drivcshsfts is invesligated. The load state and geometry existing in a shaft diner from that typically considered in the flatplate, tension-loaded eases found in the literature. A failure criteria is proposed to predict the connection strength via finite clement analysis. The effects of various design parameters on connection strength are investigated. Experimental verification of analytical results is presented for various test configurations. Goad eorrelation between analytical predictions and test results is shown to exist. 75
