Design Methodology for Bonded-Bolted Composite Joints. Volume I. Analysis Derivations and Illustrative Solutions

摘要

This report contains recent developments in three aspects of joints in advanced fibrous composite structures: (1) nonlinear analysis of adhesively-bonded stepped-lap joints and doublers, (2) multirow mechanically fastened joints in aerospace structures, and (3) nonlinear analysis of combined bonded and bolted joints. The methods developed include nonlinearities needed for metal structures as well as those for composites. The analysis are based on continuum mechanics techniques and have been coded into three Fortran IV digital computer programs A4EI, A4EJ, and A4EK respectively. The report contains explanations of the derivations of the solutions as well as sample worked problems to illustrate both the capabilities of the programs and the behavior characteristics of the real structures.
