Abstract
A two dimensional finite element model has been developed to calculate the temperature and stress distribution in a continuously cast beam blank. In the stress analysis, a thermo-elasto-plastic model was employed. The effects of a mold and the friction between a mold and beam blank were examined. The beam blank was found to deform asymmetrically during solidification due to its complicated geometry. Thermal stresses were developed at the initial stage, but decreased as solidification proceeded. The maximum tensile stress was found to develop parallel to the surface of a fillet under the constraint of a mold without friction, But the maximum tensile stress shifted toward the web with increasing friction.
