Experimental Investigations of Size Effects in Thin Copper Foils

Simons, Gerd / Dual, Jürg / Weippert, Christina / Villain, Jürgen

Abstract 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 µm. Results show a transition from ductile to a macroscopically “brittle” behavior in the range of about 20 µm.
