In the present study, we analyzed the dynamic responses of a fingertip to vibrations by extending our previously proposed three-dimensional finite element (FE) model. The FE model of the fingertip contains the essential anatomical structures of a finger, such as skin layers (dermis and epidermis), subcutaneous tissue, bone, and nail. Our analysis indicated that the fingertip has a major local resonance around 100Hz and that the vibration displacement in the soft tissues under the nail bed is less than 10% of those in the finger pad for all precompression levels and vibration range. The resonant frequency of the fingertip was found to increase from 88Hzto125Hz with the static precompression increasing from 0.5mmto2.0mm. These results suggest that structural and functional changes in vascular function will likely initiate from the fingerpad, the location that undergoes the greatest deformation during vibration exposure. The current predictions are qualitatively consistent with the physiological data collected from workers with vibration white finger.<\/jats:p>","DOI":"10.1115\/1.2947199","type":"journal-article","created":{"date-parts":[[2008,9,19]],"date-time":"2008-09-19T15:34:27Z","timestamp":1221838467000},"update-policy":"https:\/\/doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":21,"title":["Three-Dimensional Finite Element Simulations of the Dynamic Response of a Fingertip to Vibration"],"prefix":"10.1115","volume":"130","author":[{"given":"John Z.","family":"Wu","sequence":"first","affiliation":[{"name":"National Institute for Occupational Safety & Health, Morgantown, WV 26505"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kristine","family":"Krajnak","sequence":"additional","affiliation":[{"name":"National Institute for Occupational Safety & Health, Morgantown, WV 26505"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel E.","family":"Welcome","sequence":"additional","affiliation":[{"name":"National Institute for Occupational Safety & Health, Morgantown, WV 26505"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ren G.","family":"Dong","sequence":"additional","affiliation":[{"name":"National Institute for Occupational Safety & Health, Morgantown, WV 26505"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"33","published-online":{"date-parts":[[2008,7,14]]},"reference":[{"key":"2019100412551316200_c1","unstructured":"Gemne, G., and Taylor, W., 1983, \u201cForeword: Hand-Arm Vibration and the Central Autonomic Nervous System,\u201d J.
