Mathematical Modeling of Casting 7,5 Credits

Course Contents

The course aims to give the student background on how the calculation models are formulated for the simulation of phenomena associated with the casting of technical alloys (eg, Fe- Al- and Mg-based alloys). The basic heating transport problem and the coupled models are solved using the control volume-based finite difference method (FDM CV) method.
Simulation of solidification and solid phase transformation is formulated with enthalpy and kinetic methods. The results of the solidification process are linked to both microstructure and defect formaton and furthermore linked to material properties. The course provides training in the calculation of phase diagrams and thermo-physical properties for input data in casting simulation. From solidification to room temperature, the cast material undergoes thermally induced deformation. Deformation and variation of the stress state is calculated by thermo-mechanical models.
The course provides training in the transmission of the simulated material properties and the stress state to simulation programs calculating tensile strength associated with the use of cast components.
The course includes the following topics:

• Introduction of the course and outlook to research and development trends in casting simulation
• Calculation of phase diagrams and thermo-physical properties
• Formulation of kinetic models for solidification and solid phase transformation
• Formulation of the phenomena associated with solidification leading to defects (shrinkage and gas)
• Coupling of the microstructure and properties to defects
• Thermo-mechanical calculations (stress and deformation)
• Transfer of material properties, residual stresses and calculated solid models to simulation programs for strength-related calculations
