To study the mechanism of the disorders, a new rat-tail model has been established to mimic the finger vibration and pressure exposures. However, the mechanical behavior of the tail during compression needs to be better understood to improve the model and its applications. OBJECTIVE: To investigate the static and time-dependent force responses of the rat tail during compression. METHODS: Compression tests were conducted on Sprague-Dawley cadaver rat tails using a micromechanical system at three deformation velocities and three deformation magnitudes. Contact-width and the time-histories of force and deformation were measured. Additionally, force-relaxation tests were conducted and a Prony series was used to model the force-relaxation behavior of the tail. RESULTS: The rat tails\u2019 force-deformation and stiffness-deformation relationships were strongly nonlinear and time-dependent. Force\/stiffness increased with an increase in deformation and deformation velocity. The time-dependent force-relaxation characteristics of the tails can be well described using a Prony series. CONCULSIONS: We successfully quantified the static and time-dependent force responses of rat tails under compression. The identified mechanical behavior of the tail can help improve the rat-tail model and its applications.<\/jats:p>","DOI":"10.3233\/bme-230170","type":"journal-article","created":{"date-parts":[[2024,5,17]],"date-time":"2024-05-17T13:18:44Z","timestamp":1715951924000},"page":"337-349","source":"Crossref","is-referenced-by-count":1,"title":["Quantification of mechanical behavior of rat tail under compression"],"prefix":"10.1177","volume":"35","author":[{"given":"Kevin D.","family":"Moore","sequence":"first","affiliation":[{"name":", , National Institute for Occupational Safety & Health, , , USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John Z.","family":"Wu","sequence":"additional","affiliation":[{"name":", , National Institute for Occupational Safety & Health, , , USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kristine","family":"Krajnak","sequence":"additional","affiliation":[{"name":", , National Institute for Occupational Safety & Health, , , USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christopher","family":"Warren","sequence":"additional","affiliation":[{"name":", , National Institute for Occupational Safety & Health, , , USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Renguang G.","family":"Dong","sequence":"additional","affiliation":[{"name":", , National Institute for Occupational Safety & Health, , , USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","reference":[{"issue":"2","key":"10.3233\/BME-230170_ref1","doi-asserted-by":"publisher","first-page":"482","DOI":"10.3390\/vibration4020030","article-title":"A review of hand\u2013arm vibration studies conducted by US NIOSH since 2000","volume":"4","author":"Dong","year":"2021","journal-title":"Vibration"},{"key":"10.3233\/BME-230170_ref2","doi-asserted-by":"publisher","first-page":"223","DOI":"10.1124\/jpet.108.144618","article-title":"Increased oxidant activity mediates vascular dysfunction in vibration injury","volume":"328","author":"Hughes","year":"2009","journal-title":"J.
