Crack Propagation in Electron Beam Welded Ti-6Al-4V under Spectrum Loading Conditions.

Abstract

Center cracked panels of electron beam welded Ti-6Al-4V were tested under truncated F-14 aircraft wing fatigue spectra in an effort to simulate propagation of fatigue cracks from 'spike' flaws at weld intersect holes. Predictions of fatigue lives of F-14 wing carrythrough sections for various initial defect sizes were made using fracture mechanics methods. (Author)
