Assign pre-existing or user-generated materials to the model's parts, components, and
element sets.
The Assign Material dialog is dynamic and changes the list of
available parameters based on the fatigue module selected.
Note:HyperLife supports only amplitude based curves, unlike
OptiStruct which supports both amplitude and
range.
Click the Material tool.
The Assign Material dialog opens.
From the Assign Material Data tab, select either Parts
or Sets from the drop-down menu at the top of the
dialog.
Part lists or sets are obtained from the results model imported into HyperLife. The Summary field details the number of elements for
each part.
Activate the checkboxes next to the components/sets that are to be
evaluated.
Note: The Assign Material Data tab will look slightly different if you're
performing a seam weld analysis. After selecting a part or a set, click
Find Weld Toe, Root to find adjacent attached
components. You will also notice two material, standard error, and fatigue
limit categories: B and M. M stands for membrane and B stands for
bending.
Click either the Material DB tab or the My
Material tab.
Note: When creating an FOS material, the material database is not
available.
Right-click on a material and select Add to Assign Material
List.
Note: For EN calculations, a warning is shown if there is no Poisson's Ratio
available for the assigned material. Click Yes in the
dialog to proceed with a default value of 0.3.
Return to the Assign Material Data tab and select an
option from the Material drop-down menu.
The Material list is populated with the materials selected from Material
Database and My Material. A list of verified materials available in the database
for SN and EN calculation can be found at MATDAT and efatigue.com.
Optional: Define additional parameters for parts/sets by clicking in each box and
entering a value or selecting an option from a drop-down menu.
If the model results file contains thickness details, the Thickness column
should automatically be updated to reflect those values.
Tip:
Use the selection icons to quickly select all, none, or reverse your
selection of parts/sets.
Click to display the plot curve for a material.
Apply a parameter's value to all the parts/sets by right-clicking on a
parameter and selecting Apply current value to all
Parts/Sets.
