The hyperbolic form of thickness variation is considered and optimized towards the maximum rotational speed and favourable stress combinations. Radial and circumferential stress distributions in the disc both in the intermediate elastic-plastic and in the limit plastic states are obtained. As a particular case, limit elastic angular velocity parameter is derived. The influences of rotational speed as well as the disc's thickness profile on the plastic solution and size of elastic-plastic zone are demonstrated and discussed. The results obtained may be used for the correct implementation of numerical codes and preliminary engineering design. <\/jats:p>","DOI":"10.1243\/0954406jmes325","type":"journal-article","created":{"date-parts":[[2007,4,23]],"date-time":"2007-04-23T16:18:11Z","timestamp":1177345091000},"page":"137-142","source":"Crossref","is-referenced-by-count":12,"title":["Elastic-plastic stress distributions and limit angular velocities in rotating hyperbolic annular discs"],"prefix":"10.1177","volume":"221","author":[{"given":"N N","family":"Alexandrova","sequence":"first","affiliation":[{"name":"Department of Civil Engineering, University of Aveiro, Aveiro, Portugal"}]},{"given":"P M M Vila","family":"Real","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, University of Aveiro, Aveiro, Portugal"}]}],"member":"179","published-online":{"date-parts":[[2007,2,1]]},"reference":[{"key":"bibr1-0954406JMES325","doi-asserted-by":"publisher","DOI":"10.1016\/S0020-7683(99)00308-X"},{"key":"bibr2-0954406JMES325","doi-asserted-by":"publisher","DOI":"10.1115\/1.1360182"},{"key":"bibr3-0954406JMES325","doi-asserted-by":"publisher","DOI":"10.1016\/j.compstruc.2004.02.005"},{"key":"bibr4-0954406JMES325","doi-asserted-by":"publisher","DOI":"10.1016\/S0020-7403(03)00112-7"},{"volume-title":"Theory of elasticity, 3rd edition","year":"1970","author":"Timoshenko S.
