The spring-lattice models reported in the literature over the past few decades have been used to study elastic-brittle and elastic-perfectly plastic transitions. The elastic-plastic-brittle spring lattice model proposed in this thesis is an extension of the existing spring lattice models that is more generalized and can simulate a wide range of material responses. The advantages of this model are demonstrated in this thesis by a thorough parametric study focusing on elastic-plastic transitions to understand the effects of the plastic hardening ratio and strength of disorder. The difference between elastic-plastic hardening and elastic-perfectly plastic behavior in anti-plane elasto-plastic medium is confirmed in terms of weak/strong nature of neighboring interactions and their implications in describing the problem as an uncorrelated/correlated percolation. Next, the damage localization in elastic-brittle transition is demonstrated and the roughness coefficient of the crack surface is estimated to be 0.7, which matches well with the previous studies. Absence of localization in the elastic-plastic transitions is attributed to the absence of stress concentrations near the yielded sites, as opposed to elastic-brittle transitions. Finally, usefulness of the proposed model is proved through a range of material responses that can be simulated controlled by the strength of disorder distribution in yield and failure limits of the given material.","Restriction data tranferred 2014-07-01T11:11:50-05:00 Original Data Group with Access UIUC Users [automated] Release Date: 2015-02-03 13:18:53 UTC Reason: Author requested U of Illinois access only (OA after 2yrs) in Vireo ETD system"]},{"key":"dc:title","label":"Title","values":["Elastic-plastic-brittle transitions using anti-plane elastic spring lattice model"]}]}],"canonical_facts":{"dc:contributor":["Ostoja-Starzewski, Martin"],"dc:creator":["Kale, Sohan"],"dc:date":["2013-02-03T19:16:40Z","2015-02-03T11:00:38Z","2012-12"],"dc:description":["Item withdrawn by Mark Zulauf (zulauf@illinois.edu) on 2012-12-12T17:17:28Z Item was in collections: University of Illinois Theses & Dissertations (ID: 1) No. of bitstreams: 3 Kale_Sohan.pdf: 2772367 bytes, checksum: 98b630c1abd6006770e7fb347c8c4985 (MD5) Kale_Sohan.docx: 6391827 bytes, checksum: d454c74281b2d6a96ad4877bc856ea73 (MD5) Kale_Sohan.pdf: 2772821 bytes, checksum: 37b4c7669640aedaf2f1ceaa75c6ba50 (MD5)","Made available in DSpace on 2013-02-03T19:16:40Z (GMT).
