(2), but features an unknown parameter C that effectively describes the geometric change of the blunted crack tip under elastic deformation. This parameter can be identified by carrying out a least-squares curve fit for C to the range of geometries considered in our computational experiments, leading to C = 1.102. https://w3id.org/np/RAHpVXOZp5-odLFMUlo_5jQZF-j0LbTW1aT2BkvEDhods/sourceChecksum http://spdx.org/rdf/terms#algorithm http://spdx.org/rdf/terms#checksumAlgorithm_sha256 https://w3id.org/np/RAHpVXOZp5-odLFMUlo_5jQZF-j0LbTW1aT2BkvEDhods/sourceChecksum http://spdx.org/rdf/terms#checksumValue d35d9ea109c79b04ca4f44608c823ee0ab4e43a642147772bb6b89e3fe2d734f https://w3id.org/np/RAHpVXOZp5-odLFMUlo_5jQZF-j0LbTW1aT2BkvEDhods/sourceChecksum http://www.w3.org/2000/01/rdf-schema#comment Checksum of the vendored text file inputs/2009-helical-networks.txt, not of the publisher's copy. https://w3id.org/np/RAHpVXOZp5-odLFMUlo_5jQZF-j0LbTW1aT2BkvEDhods/pubinfo https://w3id.org/delphi/resource/domain/buehler-protein-materials http://www.w3.org/2000/01/rdf-schema#label buehler-protein-materials https://w3id.org/np/RAHpVXOZp5-odLFMUlo_5jQZF-j0LbTW1aT2BkvEDhods http://purl.org/dc/terms/created 2026-11-08T04:38:11.893Z https://w3id.org/np/RAHpVXOZp5-odLFMUlo_5jQZF-j0LbTW1aT2BkvEDhods http://purl.org/dc/terms/creator https://orcid.org/0009-0007-4948-9192 https://w3id.org/np/RAHpVXOZp5-odLFMUlo_5jQZF-j0LbTW1aT2BkvEDhods http://purl.org/dc/terms/license https://creativecommons.org/licenses/by/4.0/ https://w3id.org/np/RAHpVXOZp5-odLFMUlo_5jQZF-j0LbTW1aT2BkvEDhods http://purl.org/nanopub/x/hasNanopubType https://w3id.org/delphi/ontology/Claim https://w3id.org/np/RAHpVXOZp5-odLFMUlo_5jQZF-j0LbTW1aT2BkvEDhods http://purl.org/nanopub/x/introduces https://w3id.org/delphi/resource/claim/buehler-2009-helical-networks-09 https://w3id.org/np/RAHpVXOZp5-odLFMUlo_5jQZF-j0LbTW1aT2BkvEDhods http://www.w3.org/2000/01/rdf-schema#label Theodor Ackbarow et al. 2009 claim: A one-parameter blunting law (C = 1.102) predicts failure stress versus crack size https://w3id.org/np/RAHpVXOZp5-odLFMUlo_5jQZF-j0LbTW1aT2BkvEDhods https://w3id.org/delphi/ontology/domain https://w3id.org/delphi/resource/domain/buehler-protein-materials https://w3id.org/np/RAHpVXOZp5-odLFMUlo_5jQZF-j0LbTW1aT2BkvEDhods/sig http://purl.org/nanopub/x/hasAlgorithm RSA https://w3id.org/np/RAHpVXOZp5-odLFMUlo_5jQZF-j0LbTW1aT2BkvEDhods/sig http://purl.org/nanopub/x/hasPublicKey MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAyFHtPB6p0mCjDozxlOY9CmO3nBm7Te3jFbXyLmM+G1tGe47Da0jYIbhkl9Oo1ZjxmCa3LCwlEqK8gj6hEIcL4ahW30JXh9HycfKVk1bugkzMEV15tJdTzAU3sGMFnbNsn43xY2LFLy45tApkRm5byEiM7oRRrooIdwoQKnP4Wzq/bfAoJ9qvW+MGkelyOTd1jbSt+KfmT7xKmDfWzAHddUlWwMX2QJOLxDaffOteTop6ZRgPiNmPJKA/S62Gac9XtSYT3oDkZ6/nr5cxxNLpOyxTf5FPISiCe11xYO/unYjY+mwnOfA8yhJIyx1l0O9I0vpOpn+E5TvyHJV+oSTrvwIDAQAB https://w3id.org/np/RAHpVXOZp5-odLFMUlo_5jQZF-j0LbTW1aT2BkvEDhods/sig http://purl.org/nanopub/x/hasSignature a8FqsaZGgQPbcu9xbPEQAaPZZnpRTSfU3wAj/7cNkkwFCw7rzgjm1Qclh3CtI8EH+mAV5NpHxEnJVUkOKqUGgSuqw0VWafax1sFyQYR2j9WRbql+wsjBY01Xz6MsPyIQLtD9vz4ziQhY6qgulAOIUcA9wbPoHu7yOfHzF/FJIeI0BcLHSixWLEMZkHC7XxotF+mEQu2XHpORR6Vf4eCS29wUzXvxfjpM9plULfIwDTlf1Ai+W1u1LgNiAgyaNM8dlQ85cYE+XpPZCykEMVQ8xSKXWpWnFZuvKZrhJYYV5AGLY6zk4dLCjYbAgujfLEP2r3H8bzo7HJdDnn/4dphY/A== https://w3id.org/np/RAHpVXOZp5-odLFMUlo_5jQZF-j0LbTW1aT2BkvEDhods/sig http://purl.org/nanopub/x/hasSignatureTarget https://w3id.org/np/RAHpVXOZp5-odLFMUlo_5jQZF-j0LbTW1aT2BkvEDhods https://w3id.org/np/RAHpVXOZp5-odLFMUlo_5jQZF-j0LbTW1aT2BkvEDhods/sig http://purl.org/nanopub/x/signedBy https://orcid.org/0009-0007-4948-9192
