Abstract
To compute the thermal mechanical stresses and susceptibility of the material to crack during strip casting process, a coupled finite element simulation on temperature, solidification and inelastic deformation was carried out based on a unified viscous fluid model including elastic, visco-plastic deformation, thermal expansion and dilatation due to solidification. The distribution of temperature and stresses on strip surface and in nip zone was analyzed under various casting speeds. Susceptibility of the solidifying material to fracture was evaluated with a stress-crack criterion. The weakest position and effect of casting speed were clarified.
