Provided that the contact area is simply-connected profiles of arbitrary shape can be considered. Moreover, adhesion in the framework of the generalized JKR-theory can be taken into account. All results agree exactly with those given by three-dimensional contact theories. The method uses the fact that three-dimensional contact problems can be mapped to one-dimensional ones with a properly defined Winkler-foundation; henc","authors_text":"Markus He{\\ss}","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2016-01-27T16:20:50Z","title":"A simple but precise method for solving axisymmetric contact problems involving elastically graded materials"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1602.04720","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:affa940ea4be22382159c6db819847ca1e0db0e7a330d6e9e4c53d4c0812c2ee","target":"record","created_at":"2026-05-18T01:20:49Z","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":"f0949c9d584de41077ed6e2a0747536de8dc54d619c6702637423ea1c40a5976","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2016-01-27T16:20:50Z","title_canon_sha256":"e2a4aae18a2dc49494e931a605433161583087e64b5895c8ae35a061dc12659f"},"schema_version":"1.0","source":{"id":"1602.04720","kind":"arxiv","version":1}},"canonical_sha256":"1b872af8b4ed6806d675392bd2f78b3beb1b8896850212280e1e808165047505","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"1b872af8b4ed6806d675392bd2f78b3beb1b8896850212280e1e808165047505","first_computed_at":"2026-05-18T01:20:49.340772Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:20:49.340772Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Fk2Qw5KFaPT4UYBaxyhjuBzpnb39OinAEfT4ur1Uz/Owu2VGlLzjFXjHz9C/HP/XcpF8DamjBzHr/E76Pc1TAA==","signature_status":"signed_v1","signed_at":"2026-05-18T01:20:49.341179Z","signed_message":"canonical_sha256_bytes"},"source_id":"1602.04720","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:affa940ea4be22382159c6db819847ca1e0db0e7a330d6e9e4c53d4c0812c2ee","sha256:14f057f60cfe6e815435478b772bd8bbc4810c8aa84c4dd4920d9fbb35fde0cb"],"state_sha256":"590694e4d4cda9e387d588449cc330e759301a8918912fc981f4c59dbfb5dc16"}
