{ "DOI": "10.15161/oar.it/73274", "abstract": "<p>The nonlinear isotropic power hardening and the cohesive zone material (CZM) [1] criteria are applied in ANSYS [2] finite element simulations to analyze very large deformations of the GEM foils up to the failure in uniaxial tensile tests. Some data available in literature concerning both the PI/Cu and the grain boundary interfaces are utilized. The computed progressive plasticization of the perforated thin multilayer agree very well with the experimental results published by some researchers [3–6]. However the present work provides a different explanation of that behavior (already suggested in an earlier note of the author [7]) and it should be considered as a critical review concerning the conclusions of the aforementioned works.</p>", "author": [ { "family": "G.
