Traditional methods typically rely on uniaxial tensile tests, which require the cumbersome preparation of dumbbell-shaped samples for clamping in a uniaxial testing machine. In contrast, indentation-based methods, which can be conducted \\textit{in-situ} without sample preparation, have been underexplored. To characterize the hyperelastic behavior of soft materials, deep indentation is required, wher","authors_text":"Mattia Bacca, Mohammad Shojaeifard","cross_cats":["cond-mat.mtrl-sci"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.soft","submitted_at":"2025-05-28T23:24:03Z","title":"Hyperelastic characterization via deep indentation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2506.05371","kind":"arxiv","version":2},"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":"sha256:7a58358bf89e4a28715596cd9a45c1fed9dcc12ddfb1a341c2778d1f1a974c9e","target":"record","created_at":"2026-07-05T11:34:09Z","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":"97c03df5011db55b5c1d9ea02a29c08d074e7b1ce24c22ff10856f97996a76a5","cross_cats_sorted":["cond-mat.mtrl-sci"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.soft","submitted_at":"2025-05-28T23:24:03Z","title_canon_sha256":"854ce46b339122f982511fe13cb2734bf3eac2e64cbfbee81827f2042d5806e9"},"schema_version":"1.0","source":{"id":"2506.05371","kind":"arxiv","version":2}},"canonical_sha256":"f052e7fd89b3071098324beba1eb1bd03dcb417cb2ccc4903df06ee208f4cdb5","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"f052e7fd89b3071098324beba1eb1bd03dcb417cb2ccc4903df06ee208f4cdb5","first_computed_at":"2026-07-05T11:34:09.044108Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T11:34:09.044108Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"U7kyrPwlsmbpt5FEQ52uRzTkNMNe0doiUnnsstDWO6zFW6oEJR0Wz+T7HhxJEG4uaupK0q5FMdqhOSD8/h9rCQ==","signature_status":"signed_v1","signed_at":"2026-07-05T11:34:09.044572Z","signed_message":"canonical_sha256_bytes"},"source_id":"2506.05371","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:7a58358bf89e4a28715596cd9a45c1fed9dcc12ddfb1a341c2778d1f1a974c9e","sha256:d806172fa731ae7deb155c44c5db45e3967a6c1ca24f3e52eca0e062a10dddfc"],"state_sha256":"b34e359dfddbd8123791f10136b5b88f38f8dda9009f220f23a6ebdf5ecea146"}
