Numerical predictions are compared with the continuum-based laws of size effect and multifractal scaling. The yield strength is found to vary with the specimen size as ≈L^{−1/3}, which is in agreement with the multifractal scaling law, and with the inverse square of the initial crack length as ≈a^{-1/2}, according to the Griffith’s energy criterion for fracture. date: 2016-12-01 date_type: published publication: Computational Materials Science volume: 125 publisher: Elsevier pagerange: 319-326 id_number: 10.1016/j.commatsci.2016.08.016 refereed: TRUE issn: 0927-0256 related_url_url: http://dx.doi.org/10.1016/j.commatsci.2016.08.016 related_url_type: pub funders: European Research Council projects: ERC StG CA2PVM 306622 citation: Javvaji, Brahmanandam and Budarapu, Pattabhi R. and Sutrakar, V.
