    Abstract

    A methodology for certification testing of bolted hybrid aircraft structures was developed that accounts for inherent differences between composite and metal behavior. The effects of scatter and environment on static strength and fatigue life certification were characterized based on analytic correlation with test results of over 8000 carbon/epoxy specimens.
