    Experimental investigations of size effects in thin copper foils
    (Springer Dordrecht, 2004) Simons, Gerd; Dual, Jürg; Weippert, Christina; Villain, Jürgen; Ahzi, S.; Cherkaoui, M.; Khaleel, M. A.; Zbib, H. M.; Zikry, M. A.; Lamatina, B.
    This work deals with the characterization of the deformation behavior of thin copper foils with the goal of investigating size effects. Tensile tests are performed with specimens, which possess a comparable microstructure, a constant thickness/width and width/length ratio whereas the thickness varies from 10 to 250 m. Results show a transition from ductile to a macroscopically “brittle” behavior in the range of about 20 m.
