Viscosity of non-Newtonian dilatant fluid increases when applied shear\nrate exceeds the critical value. Dilatancy or shear thickening can be continuous\nor discontinuous. Many fluid properties, such as particle volume fraction and\ntemperature, influence shear thickening. A unified theory for dilatation has not yet\nbeen found, but this thesis explores a few models which are used to explain shear\nthickening. Dilatant fluid has applications especially in dampers and body armors,\nwhere it offers particularly good protection against stabs. Despite promising research\nresults, especially in protective equipment, there are still unresolved issues related to\napplications, such as considering the effect of temperature.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2024-10-17T05:49:34Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2024-10-17T05:49:34Z (GMT).
