Yield Strength Property Model: Simplified Mode Settings

This section has information about the Simplified mode configuration settings available for the Yield Strength Property Model.

The Yield Strength Model is available with the Property Model Calculator and calculates yield stress.

Yield strength is also available as a quantity when working with Plots and Tables that are successors to the Precipitation Calculator.

The Yield Strength Model returns the calculated yield strength at room temperature (per default) for the specified material using the equilibrium values calculated at temperature Intrinsic strength (i.e. Intrinsic strength is the freeze-in temperature). The Model is defined by further setting these contributions:

  • Intrinsic strength (Intrinsic strength)
  • Solid solution strengthening (Solid solution strengthening)
  • Grain boundary strengthening (Grain boundary strengthening)
  • Precipitation strengthening (Precipitation strengthening)
  • Constant strength addition (Constant strength addition)

These contributions are defined in About the Yield Strength Property Model.

For examples using the Property Model Calculator, see PM_G_04: Yield Strength, PM_G_05: Yield Strength NiAlCr, and PM_G_06: Yield Strength HEA.

For an example when it is available as an axis variable with the Precipitation Calculator, see P_01: Isothermal Precipitation of Al3Sc.

General Configuration Settings

The settings for these contributions are found on the Property Model Calculator when the Yield Strength Model is selected under General Models.

For the details about the Condition Definitions, Calculation Type, Timeout in minutes, Parallel Calculation, and other calculation associated settings, see Property Model Calculator: Configuration Window Settings.

There are settings described elsewhere when Yield Strength is selected as an axis variable for a Plot Renderer or Table Renderer that are successors to the Precipitation Calculator.

When working in the Configuration window, click the Description tab for more information about the Model.

Simplified Mode Settings

Select Simplified as the Mode.

If the following set up is not sufficient for your simulation, see the Yield Strength Property Model: Advanced Mode Settings for more detailed options.

For all calculations in Simplified Mode, the automatically applied settings are as follows:

  • Equilibrium minimization strategy is Global test preferred.
  • The matrix phase is automatically identified.
  • Burgers vector is calculated.
  • Shear modulus for the matrix is calculated.

Select the Solid solution strengthening checkbox to include solid solution strengthening in the calculation.

Click to select the Grain boundary strengthening checkbox to include calculated grain boundary strengthening (grain boundary strengthening ). Then enter the Grain size [um], which is the grain diameter in μm.

Click to select the Precipitation strengthening checkbox to include calculated precipitation strengthening (precipitation strengthening).

In Simplified Mode, the default Precipitation strength model is automatically the Deschamps model (Al-base). However, if the major element is Ni and gamma prime is present in the system, the Reppich model (Ni-base) is used instead.

Then enter the following settings.

  • Select a Precipitate from the list.
  • Enter a Mean precipitate radius. The unit is meter (m).
  • Enter a Critical radius (Critical radius), which determines the mean precipitate radius where transition between cutting and looping occurs. The unit is meter (m).

Enter a value for the Constant strength addition, Constant strength addition. The unit is MPa.
