Effect of Variances and Manufacturing Tolerances on the Design Strength and Life of Mechanically Fastened Composite Joints. Volume 2. Test Data, Equipment and Procedures

摘要

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.
