The solver handles simultaneously frictional slip (shear failure) and tensile opening (hydraulic fracture) along arbitrary intersecting fractures and faults in a linearly elastic and impermeable rock matrix. The spatial discretization combines a collocation displacement discontinuity boundary element method for quasi-static elasticity with a Galerkin finite element method for nonlinear pore-fluid diffusion along the discontinuiti"},"claims":{"count":4,"items":[{"kind":"strongest_claim","text":"The proposed framework simultaneously captures frictional slip, dilatancy, permeability evolution, and tensile opening.","source":"verdict.strongest_claim","status":"machine_extracted","claim_id":"C1","attestation":"unclaimed"},{"kind":"weakest_assumption","text":"The rock matrix is linearly elastic and impermeable, with failure governed by a poro-elastoplastic cohesive zone interface law.","source":"verdict.weakest_assumption","status":"machine_extracted","claim_id":"C2","attestation":"unclaimed"},{"kind":"one_line_summary","text":"A new implicit fully-coupled hydro-mechanical solver simulates 3D fluid-driven frictional slip and tensile opening on arbitrary intersecting fractures using combined boundary element and finite element methods.","source":"verdict.one_line_summary","status":"machine_extracted","claim_id":"C3","attestation":"unclaimed"},{"kind":"headline","text":"An implicit coupled solver simulates three-dimensional fluid-driven ruptures combining frictional slip and tensile opening on intersecting discontinuities.","source":"verdict.pith_extraction.headline","status":"machine_extracted","claim_id":"C4","attestation":"unclaimed"}],"snapshot_sha256":"1e360ba92b62f1bd1b13bf161214cbc42adb40f6aa4a421b58cb733723702330"},"source":{"id":"2605.14397","kind":"arxiv","version":1},"verdict":{"id":"41e4bc5f-27e6-4be2-8928-61226b163fc0","model_set":{"reader":"grok-4.3"},"created_at":"2026-05-15T01:48:38.659472Z","strongest_claim":"The proposed framework simultaneously captures frictional slip, dilatancy, permeability evolution, and tensile opening.","one_line_summary":"A new implicit fully-coupled hydro-mechanical solver simulates 3D fluid-driven frictional slip and tensile opening on arbitrary intersecting fractures using combined boundary element and finite element methods.","pipeline_version":"pith-pipeline@v0.9.0","weakest_assumption":"The rock matrix is linearly elastic and impermeable, with failure governed by a poro-elastoplastic cohesive zone interface law.","pith_extraction_headline":"An implicit coupled solver simulates three-dimensional fluid-driven ruptures combining frictional slip and tensile opening on intersecting discontinuities."},"references":{"count":300,"sample":[{"doi":"","year":2010,"title":"Kato, A. and Sakai, S. and Iidaka, T. and Iwasaki, T. and Hirata, N. , date-added =.
