To compute these stresses and the susceptibility of the material to crack due to these stresses, a two-dimensional finite element thermo-mechanical model has been developed. This model computes turbulent fluid flow profiles, heat transfer, solidification, and thermo-mechanically induced stresses in the solidifying body. The temperature field obtained by the fluid flow and heat transfer model is imposed as a thermal load to the system. A visco-plastic constitutive relation has been used to describe the behavior of solidifying steel. A temperature dependent ultimate strength is used to define the cracking index, which indicates the susceptibility of the material to crack. The fluid flow calculations and stress calculations are performed using commercial software programs FIDAP and ANSYS, respectively. This model was used to study two-roll melt drag method for thin strip casting of steel and horizontal twin-roll method for thin strip casting of aluminum. The effects of process parameters, such as roller speed, melt-roll heat transfer coefficient and melt superheat, on these thin strip casting processes were investigated. 1999 English text The Ohio State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=osu1391676878 http://rave.ohiolink.edu/etdc/view?acc_num=osu1391676878 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
