...J. O. Obielodan; G. D. Janaki Ram; B. E. Stucker; D. G. Taggart Two types of defects normally occur in ultrasonically consolidated parts: (i) Defects that occur between mating foils in successive layers (“type 1” defects) and (ii) defects that occur within a layer between two foils laid side...

...M. Kulakov; H. J. Rack Ultrasonic consolidation of 150 μ m thick 3003-H18 aluminum foil to a 3003-H18 build plate has been investigated. The effects of the normal load, vibrational amplitude, and sonotrode velocity on consolidation quality as characterized by the total linear weld density (LWD...

...S. Bernhardt; M. Ramulu; A. S. Kobayashi The low-velocity impact response of a hybrid titanium composite laminate, known as TiGr , was compared to that of graphite/epoxy composite. The TiGr material comprised of two outer plies of titanium foil surrounding a composite core. The composite core...

... analyzer system. In the experiments the 0.1 mm thin foil specimens of pure nickel and copper were gradually loaded toward final failure and the evolution of grain boundaries and slip bands inside grains was observed and recorded digitally via microscope and CCD camera throughout the whole time history...
