Name - Description
Name	Sets a name for the specialist durability local definition.
Description	Sets a description for the specialist durability local definition.

Analysis Setup page

Analysis Setup
Lets you select an analysis template, inspect or define values for durability simulation objects, and add durability simulation objects.
Analysis Template	Specifies the analysis template.Inherit from SolutionUses the same analysis template as the one you defined for the specialist durability solution process.Stress LifeSuitable for isotropic material parts that are subjected to stresses with values below or close to the elastic limit, and exhibit high-cycle failure.Strain LifeSuitable for isotropic material parts that are subjected to local plasticity and typically exhibit low-cycle failure.InterlaminarSuitable for damage interface materials between plies of long-fiber composites, or between arbitrary parts. It determines the delamination durability of the material using a progressive failure approach.Van PaepegemSuitable for orthotropic materials that are assigned to balanced 2D woven fabrics. It determines the durability of the fiber and matrix system using a progressive failure approach.Short Fiber Master SN CurveSuitable for orthotropic materials representing short-fiber composite materials. It determines the durability of the fiber and matrix system using an SN curve approach.Nominal Stress Seam Weld, Notch Stress Seam WeldSuitable for seam weld fatigue analysis. The nominal stress approach uses base flange solver stresses, whereas the advanced notch stress approach internally computes the weld stresses from the solver force results.Force Based Spot Weld, Stress Based Spot WeldSuitable for spot weld fatigue analysis. The force based approach recovers solver beam or constraint element forces and back-calculates stresses, whereas the stress based approach extracts flange solver stresses.When you select an analysis template, the software automatically loads the durability simulation objects into the durability simulation objects list as per the analysis template settings, which include required and optional parameters.
Durability Simulation Objects
Hide Inherited Objects	Hides the simulation objects whose value is inherited from the durability simulation objects list.
Add to List	Opens the Durability Simulation Objects dialog box that lets you add durability simulation objects, filtered to those specified in the analysis template, to the durability simulation objects list.
Reset to Default	Resets the durability simulation objects list, as per the analysis template settings, and removes all your modifications. A confirmation warning prevents an unintended reset.
Add Missing Objects from Solution	Adds the simulation objects that are missing from the specialist durability solution process to the list.
Durability simulation objects list	List all the required and optional durability simulation objects that define the parameters and the behavior of the solution process.This list is generated based on the selected analysis template. Changing the analysis template potentially changes the list of simulation objects:Missing simulation objects are added according to the settings of the analysis template.The simulation objects that are configured to be present in both analysis templates are not removed. However, the values of those objects are updated to the default value of the new analysis template, except when the default value in the new analysis template is None, and when you modified the object before the change.Any simulation object that is not configured to be part of the new analysis template is removed from the list.The list displays the following information that you can sort using the column headings:TypeDisplays the durability simulation object type.ObjectDisplays the value of the durability simulation object.OptionIndicates whether the durability simulation object is required or optional. This depends on the analysis template.Status Indicates that the durability simulation object value is defined. Indicates that a required durability simulation object value is set to None. You must assign a value as it is a required object. Indicates that the durability simulation object value is inherited from the specialist durability solution process. Indicates that the durability simulation object is optional and its value is not defined. When you right-click a simulation object from the list, the following commands appear: InspectOpens the Durability Simulation Objects dialog box that lets you inspect the properties of the selected durability simulation object.Choose Simulation ObjectOpens the Durability Simulation Objects dialog box, filtered by the selected object type, and lets you select, edit, inspect, or create a durability simulation object of that type.Set to InheritedInherits the simulation object value from the specialist durability solution process.InformationOpens an information window that lists the simulation object property values.Note: You cannot remove a simulation object from the list, however, you can set its value to none.
Type	Displays the type of the durability simulation object that you select from the list.
Object	Specifies a value of the durability simulation object that you select from the list.Select None if you want the solution process to ignore a selected durability simulation object.
Manage Objects	Opens the Durability Simulation Objects dialog box, filtered by the selected object type, and lets you select, edit, inspect, and create a durability simulation object of that type.

Location page

Location
Location	Specifies how to define the content of the location for the local definition.NoneLets you skip defining a location for the local definition. This is usefull, for example, if you want to define the location in a function definition that you will later create from the local definition.Select ElementsLets you select elements.Seam Weld Set SelectionLets you select seam weld sets.Spot weld set selectionLets you select spot weld sets.
Select Elements
Available when Location is set to Select Elements.
All Model	Available when the Remaining Structure check box is cleared.Selects the entire model.
Remaining Structure	Available when the All Model check box is cleared.Select the elements that are not selected in other local definitions.
Group Reference	Available when the All Model and Remaining Structure check boxes are cleared.Lets you select one or more groups of elements for the local definition. For more information, see Group Reference options.
Select Elements	Available when the Remaining Structure and Group Reference check boxes are cleared.Lets you select the elements for the local definition from the graphic window.
Stacked Smart Selector Methods	Opens the Smart Selector Methods dialog box where you can specify a progression of smart selection filters.For more information, see Smart Selector Methods dialog box.
Element Labels
Available when Location is set to Select Elements and the Select All and Group Reference check boxes are cleared.
Labels	Lets you select the elements using their labels.Use a space or comma to separate your entries.Use a colon or a dash to add a range of element labels.For example, enter 1:10 or 1-10 to add all the element labels from 1 to 10.Use colons to add an incremented range of element labels.For example, enter:1:9:2 to add element labels 1, 3, 5, 7, 9.1:10:2 to add element labels 1, 3, 5, 7, 9, 10.10:1:-2 to add element labels 10, 8, 6, 4, 2, 1.Press enter or click Select to add your entries.To edit your selection, click Edit Element Selection .
Seam Weld Set Selection or Spot Weld Set Selection
Available when Location is set to Seam Weld Set Selection or Spot Weld Set Selection.
Seam Weld Set Selection or Spot Weld Set Selection	Opens the Set Selection dialog box that lets you select weld sets.
Seam Weld Set Selection list or Spot Weld Set Selection list	Lists the selected weld sets.

Material Definition page

Material Definition
Material	Specifies the materials for the fatigue analysis. The available options are:Inherit from SolutionUses the material selection made in the specialist durability solution process for the local definition.Inherit from SIM/FEMAllows the solution process to access the materials, as per their assignment in the FEM.Local materialsLets you select a single local material, which is assigned to all the elements in the solution process.
Select Material	Opens the Material List dialog box that lets you create, modify, or select a material from the local or library materials.
Plot Materials	Available when you select a local material from the Material list.Lets you select the type of the material plot to display:Stress-LifePlots the material's SN-curve on a log-log scale. The X-axis is the fatigue life, or the number of cycles to failure, and the Y-axis is the stress amplitude. For more information, see Defining SN-curves.Ramberg-OsgoodPlots the stress amplitude versus the strain amplitude on a linear-linear scale. For more information on modeling of the stress-strain material behavior in the strain-life analysis, see Local stress-strain behavior.Manson-Coffin-MorrowPlots the strain amplitude versus the number of cycles to failure, based on the Manson-Coffin-Morrow equation, on a log-log scale. For more information on how the fatigue life, which is the number of cycles to failure, correlates to the strain amplitude, see Constant amplitude life curves.Strain-LifePlots both Ramberg-Osgood and Manson-Coffin-Morrow curves as stacked graphs.If any of the required material properties are not defined, the software displays a warning message. For more information on the required durability material properties for the stress life and strain life analysis, see Required material properties for specialist durability analysis.Note: Plot materials does not support the materials with temperature dependent properties.Plot materials excludes the specified R-Ratio durability property for the material, and sets the R-Ratio value to -1 for generating the plots.
