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.
