ANNUAL REPORT 2005 Meeting date: June 1, 2005 Solidification Stress Modeling using ABAQUS * Seid Koric Brian G. Thomas •Engineering Applications Analyst, NCSA Ph. D. Candidate Department of Mechanical Industrial Engineering University of Illinois at Urbana-Champaign Objectives To predict the evolution of temperature, shape, stress and strain distribution in the solidifying shell in continuous casting mold by a nonlinear multipurpose commercial finite element package with an accurate approach. Validate the model with available analytical solution and benchmarks with in-house code CON2D specializing in accurate modeling of 2D continuous casting. To enable new model to be applied to the continuous casting problems by incorporating even more complete and realistic phenomena. To perform a unique realistic 3D thermal stress analysis of solidification of the shell of a thin slab caster that can accurately predict the 3D mechanical state in some critical regions important to crack formation. Apply FE results to predict the effects of casting speed on total strain evolution, to predict maximum casting speed to avoid bulging, to predict damage strains and transverse and longitudinal cracks, to find ideal taper and more.
