We show that, below a certain substrate temperature, fractures appear on the frozen pancake and the crack patterns change from a 2D fragmentation regime to a hierarchical fracture regime as the thermal shock is stronger. The different regimes are discussed and the transition temperatures are estimated through classical fracture scaling arguments. Finally, a phase diagram presents how these regimes can be controlled by the drop impact para","authors_text":"Christophe Josserand, Elisabeth Ghabache, Thomas S\\'eon","cross_cats":["cond-mat.soft"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.flu-dyn","submitted_at":"2016-05-09T15:54:21Z","title":"Frozen impacted drop: From fragmentation to hierarchical crack patterns"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1605.02636","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":"sha256:03dfe2401106892d372abff5d412130753bec625473be6e5bca8fadbcaefbcaa","target":"record","created_at":"2026-05-18T01:08:17Z","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":"c2c2f8661081b3449511cbad94dcedf5a5a9b5630a4653cfc2f173e0437a9acd","cross_cats_sorted":["cond-mat.soft"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.flu-dyn","submitted_at":"2016-05-09T15:54:21Z","title_canon_sha256":"489c22a1b0f8857db1cba8e7299f7852f52ca08c99d54b2d673ba9477c8b0dc4"},"schema_version":"1.0","source":{"id":"1605.02636","kind":"arxiv","version":1}},"canonical_sha256":"57d3cb268e9139b7f04f2541540d5f91af5cd238d15af4786d8cb64f00d420e3","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"57d3cb268e9139b7f04f2541540d5f91af5cd238d15af4786d8cb64f00d420e3","first_computed_at":"2026-05-18T01:08:17.227710Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:08:17.227710Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"HVnE8yuJGBYq8gUr5o5mJGnQb2jKXw/SsGVXDBGEBH2eib1vMwTpDULXem7FJMv7Wtj8M65hg22m14UxBjJAAA==","signature_status":"signed_v1","signed_at":"2026-05-18T01:08:17.228387Z","signed_message":"canonical_sha256_bytes"},"source_id":"1605.02636","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:03dfe2401106892d372abff5d412130753bec625473be6e5bca8fadbcaefbcaa","sha256:d57eb2ee30f5f0dc2706340423444f7c215bdd4c83eabde36dd04363f4cc3f5e"],"state_sha256":"afd8b16c21e5b3080a437d99fbad6e1ea0831c9d762b1cba8b140ee2dcbb1962"}
