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>", "headline": "Asymmetric Elastoplastic Behavior and Failure of GEM Foils", "identifier": "https://doi.org/10.15161/oar.it/73274", "image": "https://zenodo.org/static/img/logos/zenodo-gradient-round.svg", "keywords": [ "thin films, polymers, cohesive zone material, adhesion, grain boundaries." ], "license": "https://creativecommons.org/licenses/by/4.0/", "name": "Asymmetric Elastoplastic Behavior and Failure of GEM Foils", "url": "https://www.openaccessrepository.it/record/73274" }
