Mec Fit

This MEC Fit utility is used to customize plastic mechanical properties for individual phases by plotting stress-strain curve data from any three plastic parameters, strain, strain-rate, temperature and/or carbon. The utility can also fit data from experimental stress strain data. This utility can also plot the mechanical parameters for a specific material and phase from the DANTE material database.

Use Case

One use for the Mec Fit utility is plot the stress strain curve for any phase and material from the DANTE material database. To plot the stress strain curve, select the phase from the file drop down menu by going to File --> Load MEC File --> MEC parameters --> Steel --> Austenite. Next, select the S10XX material from the DANTE material database to load in the 27 mechanical parameters.

Next, select Plot For Single Point as the Processing Method and click analyze to plot the S10XX Austenite mechanical properties. This processing method does not need a data file, but instead, will need to define the Max Strain, Strain Rate, Temperature, and Carbon Level inside the Experimental Data tab.

Click plot and display the stress strain curve for the mechanical properties for 1020 material found in the DANTE material database.

Next, by adjusting the carbon level, we can see how this will effect the mechanical properties, specifically for the Austenite phase.

With experimental data, the Mec Fit utility can also be used to fit for the parameters for any phase or material inside the DANTE material database.
