Modeling fluid‐solid thermomechanical interactions in casting processes

An integrated formulation for the analysis of casting processes is presented in this work. This model involves the description of the evolution and the coupled interactions of the flow, thermal and mechanical fields occurring during the liquid‐solid transformation of the solidifying metal. The corresponding discretized formulation is solved in the context of a fixed‐mesh finite element method. Numerical results applying this methodology in two cylindrical casting specimens are first presented to assess the influence of different phenomena occurring during the process. Moreover, these simulations are compared with available experimental data.
