Abstract

A coupled computational thermo-mechanical model has been developed to simulate the continuous casting of complex shaped sections, such as used for steel beam blanks. An efficient numerical procedure to integrate the constitutive equations at the local levelis combined with a global finite-element solution oftemperature and stress. It includes realistic constitutive behavior of the liquid/mushy zone, delta-ferrite, and austenite phases of the solidifying steel shell using a fixed grid approach. Heat transfer is computed in the shell, the complex-shaped mold, and across the in terfacial gap between them, and is fully-coupled with the stress model to include the effect of shell shrinkage and gap formation on lowering the heat flux. Current work, to incorporate results from turbulent thermal-fluid flow simulations of liquid pool into this thermal-stress model, is introduced
