Moreover, the presence of vugs may have non-trivial impacts on the geomechanical behavior of rock. How to quantify and analyze such effects is still an opening problem. To this end, we derive a macroscopic poroelastic model for a single-phase viscous fluid flow through a deformable vuggy porous medium. At first, a vuggy porous medium is divided into two parts: the porous matrix and vugs. Then, we model the hydro-mechanical coupling process on the fine scale using Biot's equations with","authors_text":"Herv\\'e Jourde, Jun Yao, Tao Huang, Xiaoguang Wang, Xu Zhou, Zhaoqin Huang","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.comp-ph","submitted_at":"2018-04-12T05:56:19Z","title":"Homogenization of a Biot-Stokes system modeling deformable vuggy porous media"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1804.04329","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":"sha256:4001d1b376c62cbe4e099d861ee47a004819285ed0a67960503e671c454f5427","target":"record","created_at":"2026-05-18T00:18:39Z","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":"e2a399ca796d1074ff9feec7f95b2adcf0340fa9c407e0ff02d0e88ea96301f2","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.comp-ph","submitted_at":"2018-04-12T05:56:19Z","title_canon_sha256":"e4aa8ec31fa5c467776ab524a13acc424dbd38c1469247d1fe61905993dadd52"},"schema_version":"1.0","source":{"id":"1804.04329","kind":"arxiv","version":1}},"canonical_sha256":"a4516b91ca4992676094fe97ba4bade52cd7968ee1fc2ea2cf0d7253e0c7b248","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"a4516b91ca4992676094fe97ba4bade52cd7968ee1fc2ea2cf0d7253e0c7b248","first_computed_at":"2026-05-18T00:18:39.869458Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:18:39.869458Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"QohwHL0bN3VyQSYFe3EFtQ/TH7cZ4KyrvBKAwOGOM3CeV4qDvy32b1mCwSD+Ux0cmTvF4+RWL4Lw5nOl9EmyBg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:18:39.869968Z","signed_message":"canonical_sha256_bytes"},"source_id":"1804.04329","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:4001d1b376c62cbe4e099d861ee47a004819285ed0a67960503e671c454f5427","sha256:b65c9706ea1a0b88d3a9b30737eb81c9882f8bd50a22beedc0be00f1409be9a8"],"state_sha256":"a2fa283d01c36498f45f0516fe29c07b067736936c0cd9b0b0406526b841aa42"}
