Thermomechanical-Microstructural Simulation of the Nodular Cast Iron Solidification Process

Patricia M. Dardati, Diego J. Celentano, Fernando D. Carazo, Luis A. Godoy


This paper presents a thermomechanical-microstructural formulation for the analysis of the solidification process of nodular cast irons of eutectic composition. This formulation is defined in a finite strain thermoplasticity framework considering microstructure-based liquid-solid phase-change
effects. The performance of this model is evaluated in the analysis of a solidification test, for which laboratory measurements are compared with the corresponding numerical results.
