| dc.description | ABSTRACTA study was made to investigate the feasibility of superplastically forming corrugated panels with beaded webs and to demonstrate the structural integrity of these panels by testing. The test panels in the study consisted of superplastically formed titanium alloy Ti-6Al-4V half-hat elements that were joined by weld-brazing to titanium alloy Ti-6Al-4V caps to form either single-corrugation compression panels or multiple-corrugation compression panels. Stretching and subsequent thinning of the titanium sheet during superplastic forming was reduced by approximately 35 percent with a shallow half-hat die concept instead of a deep die concept and resulted in a more uniform thickness across the beaded webs. The completed panels were tested in end compression at room temperature and the results compared with analysis. The heavily loaded panels failed at loads approaching the yield strength of the titanium material. At maximum load, the caps wrinkled locally accompanied with separation of the weld-braze joint in the wrinkle. None of the panels tested, however, failed catastrophically in the weld-braze joint. Experimental test results were in good agreement with structural analysis of the panels. |
