Beyond the characteristic size of disorder, the roughness profiles are found to exhibit self-affine scaling features evolving with porosity. Starting from a null value and increasing the porosity, we quantitatively modify the self-affine scaling properties from a","authors_text":"Daniel Bonamy, Harold Auradou, Jonathan Bares, Lamine Hattali, Tristan Cambonie, V\\'eronique Lazarus","cross_cats":["cond-mat.soft"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2015-01-16T16:20:00Z","title":"Effect of the porosity on the fracture surface roughness of sintered materials: From anisotropic to isotropic self-affine scaling"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1504.03998","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:9fcd0754174499658439c5c5c6a0f1b78d2ed8b7f09d3f646b158ac309ce7895","target":"record","created_at":"2026-05-18T02:18:41Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"3579879f9289ebbc72af0ee9daa5fd11c2eea84fb9fdd067d7d069f222bbbef8","cross_cats_sorted":["cond-mat.soft"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2015-01-16T16:20:00Z","title_canon_sha256":"b464e58d50b9dd259a5d1a4c18caa99121d8c5e434d50a02ab1758403896b56e"},"schema_version":"1.0","source":{"id":"1504.03998","kind":"arxiv","version":1}},"canonical_sha256":"ff45999560d87a85b157c1a297c13fc86f4d0701b6b319e4732a29ee3728c706","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ff45999560d87a85b157c1a297c13fc86f4d0701b6b319e4732a29ee3728c706","first_computed_at":"2026-05-18T02:18:41.465507Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:18:41.465507Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"akwj3sbor63fYho2l34WlUkUQxY39vS3iB0ejVgdauCHNqgTI9i12RjMpl6L+l2xPslg+D8Q1xflb4uN7KfiDQ==","signature_status":"signed_v1","signed_at":"2026-05-18T02:18:41.466175Z","signed_message":"canonical_sha256_bytes"},"source_id":"1504.03998","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:9fcd0754174499658439c5c5c6a0f1b78d2ed8b7f09d3f646b158ac309ce7895","sha256:83b13363d04dc946c2af5a234d013eb6eb842126e105e88f4ec57e363c8b4409"],"state_sha256":"0a1858170b401507a93d28ab4b4280fc8224654ddd060afdb8e164f63f64ba3e"}
