Both armchair and zigzag edged graphene nanoribbons are considered. We discuss results obtained through two different theoretical approaches, viz. density functional methods and molecular dynamics atomistic simulations using empirical force fields especially designed to describe interactions within graphene sheets. Apart from the stress-strain curves, we calculate several elastic parameters, such as the Young\u2019s modulus, the third-order elastic modulus, the intrinsic strength, the fracture strain, and the Poisson\u2019s ratio versus strain, presenting their variation with the width of the nanoribbon.<\/jats:p>","DOI":"10.3390\/ma14175042","type":"journal-article","created":{"date-parts":[[2021,9,6]],"date-time":"2021-09-06T13:09:25Z","timestamp":1630933765000},"page":"5042","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Width Dependent Elastic Properties of Graphene Nanoribbons"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7763-718X","authenticated-orcid":false,"given":"George","family":"Kalosakas","sequence":"first","affiliation":[{"name":"Materials Science Department, University of Patras, GR-26504 Rio, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5589-7930","authenticated-orcid":false,"given":"Nektarios N.","family":"Lathiotakis","sequence":"additional","affiliation":[{"name":"Theoretical and Physical Chemistry Institute, National Hellenic Research Foundation, Vass.
