GetFatigueSNCurve Method (ICWMaterial)

Gets the fatigue S-N curve data for user-defined curve sources.

.NET Syntax

Visual Basic (Declaration) 
Function GetFatigueSNCurve( _
   ByVal NIndex As System.Integer, _
   ByRef DStressRatio As System.Double _
) As System.Object
Visual Basic (Usage) 
Dim instance As ICWMaterial
Dim NIndex As System.Integer
Dim DStressRatio As System.Double
Dim value As System.Object
 
value = instance.GetFatigueSNCurve(NIndex, DStressRatio)
C# 
System.object GetFatigueSNCurve( 
   System.int NIndex,
   out System.double DStressRatio
)
C++/CLI 
System.Object^ GetFatigueSNCurve( 
&   System.int NIndex,
&   [Out] System.double DStressRatio
)

Parameters

NIndex
0-based S-N curve data index
DStressRatio
Stress ratio

Return Value

Array of S-N curve data (see Remarks)

Remarks

This method is valid only if ICWMaterial::SNCurveSource is set to swsMaterialSNCurveSource_e.swsMaterialSNCurveSourceUserDefined.

 

Array of S-N curve data:

[ n, x1, y1, x2, y2, x3, y3,...xn, yn ]

where:

  • n = number of xi,yi pairs

  • x1 = number of cycles for point 1

  • y1 = alternating stress for point 1

  • ...

  • xn = number of cycles for point n

  • yn = alternating stress for point n

See the SOLIDWORKS Help topic, Material Dialog Box - Fatigue SN Curves Tab, for more information about S-N curve equations.
