Abstract:

The subject of this program was structural evaluation of mechanically fastened composite joints. Program objectives were 1 development and verification by test of improved static strength methodology 2 experimental evaluation of the effects of manufacturing anomalies on joint static strength and 3 experimental evaluation of joint fatigue life. Program activities included 1 A literature survey which was performed to determine the state-of- the-art in design and analysis of bolted composite joints 2 Strength data were obtained through an experimental program to evaluate the effects of twelve joint design variables 3 Effects of seven manufacturing and service anomalies on joint strength were evaluated experimentally and compared with strength data 4 Bolted composite joint durability was evaluated and 5 Required data reduction, methodology development and correlation, and necessary documentation were performed.
