Parameters

NIndex

0-based S-N curve data index

DStressRatio

Stress ratio

VarFatigueSNCurveData

Array of S-N curve data (see Remarks)

ErrorCode

Error as defined in swsMaterialFatigueSNCurveError_e

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

VarFatigueSNCurveData:

[ 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
