LDPM is formulated in the framework of discrete mechanics and it simulates the heterogeneous deformation of cemented granular systems by means of discrete compatibility/equilibrium equations defined at the grain scale. A numerical strategy is proposed to generate a realistic microstructure based on the actual grain size distribution of a sandstone and the capabilities of the method are illustrated with ","authors_text":"Gianluca Cusatis, Giuseppe Buscarnera, Shiva Esna Ashari","cross_cats":["physics.geo-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2016-05-20T00:22:16Z","title":"Lattice Discrete Particle Model (LDPM) for pressure-dependent inelasticity in granular rocks"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1605.06178","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":"sha256:87917ded4f15d0b2325ba15bda1c87fbc33a72e8fd23837413420593998daedd","target":"record","created_at":"2026-05-18T01:14:19Z","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":"f0b461a741947884456128a8e11b2b459ac5d750c7c2ec45fd591116c6fe3fcc","cross_cats_sorted":["physics.geo-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2016-05-20T00:22:16Z","title_canon_sha256":"e1b0cb7081f82baad9ba6ea56403909a7df2e24e5a61bd858b0df04947dfd361"},"schema_version":"1.0","source":{"id":"1605.06178","kind":"arxiv","version":1}},"canonical_sha256":"d295ded10d7ca29ab9ac94e093c7fc29c0a509d6a5eee84597a528da5d8af3b2","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d295ded10d7ca29ab9ac94e093c7fc29c0a509d6a5eee84597a528da5d8af3b2","first_computed_at":"2026-05-18T01:14:19.734988Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:14:19.734988Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"JTy7LYIL+7Q5zx0qHRU2N7IzDBFIDTUWOjj0Vns0InxZ4JVkfXd8graHy1aszv3GBLG/JmJ9SzgM0fkMFFh3AQ==","signature_status":"signed_v1","signed_at":"2026-05-18T01:14:19.735726Z","signed_message":"canonical_sha256_bytes"},"source_id":"1605.06178","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:87917ded4f15d0b2325ba15bda1c87fbc33a72e8fd23837413420593998daedd","sha256:5d7259e7302c407e70e1eb4157556fb451d3394b7102ad497283ff48935f29da"],"state_sha256":"863b93631ae08504ed294b27e362a12b0f728837e04e4bdf7c1cc863d2c4cc58"}
