Efficient Thermo-Mechanical Model for Solidification Processes and Its Applications in Steel Continuous Casting

182 p.Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 2006.The model is then improved to add coupling of heat flow and stress generation that are increment-wise coupled through the size of the interfacial gap. Coupled results are first verified with a solidifying slice, and then quantitatively against the CON2D 2D model of billet casting by fully employing Abaqus thermal and mechanical contact capabilities. Another coupled 2D model of bloom beam blank casting, known for a very challenging geometry, is solved for the simultaneous evolution of deformation, temperature, and stress. Finally, a large scale 3D simulation of a thin slab caster with a funnel, first of that kind ever conducted, is performed to correctly reproduce the 3D mechanical state in casting process with extremely complex geometry and loading conditions.U of I OnlyRestricted to the U of I community idenfinitely during batch ingest of legacy ETD
