The deep-drawability of a sheet metal blank is strongly influenced by the tribological conditions prevailing in deep-drawing process. Therefore, new methods to influence tribology represent an important research topic. In this work, application process-integrated lubrication process investigated. Most promising geometries channels and outlet openings are first identified means numerical simulat...

The infectious form of the scrapie amyloid (prion) precursor, PrPSc, is a host-derived protein and a component of the infectious agent causing scrapie. PrPSc and the carboxyl-terminal proteinase K resistant core, PrP27-30, have the potential to form amyloid as a result of a post-translational event or conformational abnormality. We have studied the conformational transitions of both proteins re...

The design of multi stage deep drawing processes requires the evaluation of many process parameters such as the intermediate die geometry, the blank shape, the sheet thickness, the blank holder force, friction, lubrication etc..These process parameters have to be determined for the optimum forming conditions before the process design. In general sheet metal forming may involve stretching drawin...

Recent failure information from research teams in NASA Langley and others has shown that CTOA based fracture models calibrated on large C(T) and M(T) specimens can be transferred successfully to cracked aircraft fuselage structures for the assessment of their residual strength. A major difficulty that could limit the more extensive use of this failure parameter is its experimental measurement e...
