Week - 9 Material Modeling from Raw Data
Use the diagram of the true stress-strain curve of graphite iron casting. Two curves are there for different material structures. Students need to pick any one of them and use the data to create either a MAT_024 or MAT_018 material model and then validate it.
Use a data digitizer to create the data points from the curve and use the following video for reference:
Here is the workflow:
- Extract the data from the diagram
- Clean the data and visually confirm that it matches the original data and the elastic modulus is 20.9E+06 psi.
- Convert the data to (kg-mm-ms) unit system
- Process the data and create the material as demonstrated
- Use the material model with a dogbone specimen and validate the same.
