To inform headform design and to verify that such substitution is valid, the force-deformation response of the human head with boundary conditions relevant to cervical spine head-first impact models is required. There are currently no biomechanics data that characterize the force-deformation response of the isolated head supported at the occiput and compressed at the vertex by a flat impactor. The effect of impact velocity (1, 2 or 3\u00a0m\/s) on the response of human heads (<jats:italic>N<\/jats:italic>\u2009=\u200922) subjected to vertex impacts, while supported by a rigid occipital mount, was investigated. 1 and 2\u00a0m\/s impacts elicited force-deformation responses with two linear regions, while 3\u00a0m\/s impacts resulted in a single linear region and skull base ring fractures. Peak force and stiffness increased from 1 to 2 and 3\u00a0m\/s. Deformation at peak force and absorbed energy increased from 1 to 2\u00a0m\/s, but decreased from 2 to 3\u00a0m\/s. The data reported herein enhances the limited knowledge on the human head\u2019s response to a vertex impact, which may allow for validation of surrogate head models in this loading scenario.<\/jats:p>","DOI":"10.1007\/s10439-023-03358-z","type":"journal-article","created":{"date-parts":[[2023,9,21]],"date-time":"2023-09-21T14:03:48Z","timestamp":1695305028000},"page":"2897-2907","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["The Structural Response of the Human Head to a Vertex Impact"],"prefix":"10.1007","volume":"51","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4402-834X","authenticated-orcid":false,"given":"Darcy W.","family":"Thompson-Bagshaw","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0633-2482","authenticated-orcid":false,"given":"Ryan D.","family":"Quarrington","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew M.","family":"Dwyer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nigel R.","family":"Jones","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0995-1182","authenticated-orcid":false,"given":"Claire F.","family":"Jones","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2023,9,21]]},"reference":[{"key":"3358_CR1","first-page":"2009","volume":"100","author":"DL Allsop","year":"1991","unstructured":"Allsop, D.
