At long times, the evolution of the viscoelastic thread deviates from self-similar exponential decay and the competition of elastic, capillary, and inertial forces leads to the formation of a periodic array of beads connected by axially uniform ligaments. This configuration is itself unstable and successive instabilities propagate from the necks connecting the beads and the ligaments. This iterated process results in the development of multiple generations of beads in agreement with the predictions of Chang, Demekin, and Kalaidin [\u201cIterated stretching of viscoelastic jets,\u201d Phys. Fluids\u200811, 1717 (1999)] although experiments yield a different recursion relation between successive generations. At long times, finite molecular extensibility truncates the iterated instability and axial translation of the bead arrays along the interconnecting threads leads to a progressive coalescence before the rupture of the filament.<\/jats:p>","DOI":"10.1063\/1.1949197","type":"journal-article","created":{"date-parts":[[2005,7,19]],"date-time":"2005-07-19T22:00:48Z","timestamp":1121810448000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":140,"title":["Iterated stretching and multiple beads-on-a-string phenomena in dilute solutions of highly extensible flexible polymers"],"prefix":"10.1063","volume":"17","author":[{"given":"M\u00f3nica S.
