Fatigue". ## Constructors ### FatigueParameter() ```csharp public FatigueParameter() ``` ## Properties ### AnalysisMethod Gets or sets the analysis method used for EN (Strain-Life) fatigue analysis. ```csharp [Obsolete("This property will be deprecated in the near future.")] public AnalysisMethodEN AnalysisMethod { get; set; } ``` #### Property Value AnalysisMethodEN #### Examples For an example that includes this property, see the [Class FatigueParameter](VM.Operations.Post.FatigueParameter.md). #### Remarks This property is applicable only when the is set to EN. It determines the specific method used for strain-life fatigue analysis, such as: - - - ### AnalysisType Gets or sets the type of fatigue analysis to be performed. ```csharp [Obsolete("This property will be deprecated in the near future.")] public FatigueAnalysisType AnalysisType { get; set; } ``` #### Property Value FatigueAnalysisType #### Examples For an example that includes this property, see the [Class FatigueParameter](VM.Operations.Post.FatigueParameter.md). #### Remarks This property determines the method used for fatigue analysis, such as Stress-Life (SN) or Strain-Life (EN). Available values for - - ### BodyName Gets or sets the name of the body for which fatigue analysis is performed. ```csharp [Obsolete("This property will be deprecated in the near future.")] public string BodyName { get; set; } ``` #### Property Value string #### Examples For an example that includes this property, see the [Class FatigueParameter](VM.Operations.Post.FatigueParameter.md). #### Remarks This property is required to identify the specific body in the fatigue analysis process. ### MaterialName Gets or sets the name of the material used in the fatigue analysis. ```csharp [Obsolete("This property will be deprecated in the near future.")] public string MaterialName { get; set; } ``` #### Property Value string #### Examples For an example that includes this property, see the [Class FatigueParameter](VM.Operations.Post.FatigueParameter.md). #### Remarks This property is required to specify the material properties for the fatigue analysis process. ### MeanStressCorrection Gets or sets the mean stress correction method used in the fatigue analysis. ```csharp [Obsolete("This property will be deprecated in the near future.")] public MeanStressCorrection MeanStressCorrection { get; set; } ``` #### Property Value MeanStressCorrection #### Examples For an example that includes this property, see the [Class FatigueParameter](VM.Operations.Post.FatigueParameter.md). #### Remarks This property is used to define how mean stress is accounted for during the fatigue analysis process. ### PlasticityCorrection Gets or sets the plasticity correction method used in the fatigue analysis. ```csharp [Obsolete("This property will be deprecated in the near future.")] public PlasticityCorrection PlasticityCorrection { get; set; } ``` #### Property Value PlasticityCorrection #### Examples For an example that includes this property, see the [Class FatigueParameter](VM.Operations.Post.FatigueParameter.md). #### Remarks This property is used to define how plasticity effects are accounted for during the fatigue analysis process. It is applicable when strain-based fatigue analysis is performed. ### Scale Gets or sets the scale factor used in the fatigue analysis. ```csharp [Obsolete("This property will be deprecated in the near future.")] public double Scale { get; set; } ``` #### Property Value double #### Examples For an example that includes this property, see the [Class FatigueParameter](VM.Operations.Post.FatigueParameter.md). #### Remarks This property is used to adjust the magnitude of the analysis results, allowing for scaling based on specific requirements. ### StressStrainCombinationType Gets or sets the type of stress-strain combination used in the fatigue analysis. ```csharp [Obsolete("This property will be deprecated in the near future.")] public StressStrainCombinationType StressStrainCombinationType { get; set; } ``` #### Property Value StressStrainCombinationType #### Examples For an example that includes this property, see the [Class FatigueParameter](VM.Operations.Post.FatigueParameter.md). #### Remarks This property is used to define how stress and strain are combined during the fatigue analysis process.
