Adds a failure interval and associated stress level to the data set.

Method Syntax

• AddFailureInterval( ByVal StartValue As Double , ByVal EndValue As Double , ByVal NumberInGroup As Integer , ByRef Stress() As Object )
• AddFailureInterval( ByVal StartValue As Double , ByVal EndValue As Double , ByVal NumberInGroup As Integer , ByRef Stress1 As Object )
• AddFailureInterval( ByVal StartValue As Double , ByVal EndValue As Double , ByVal NumberInGroup As Integer , ByRef Stress1, Stress2 As Object )

Parameters

StartValue The starting value of this failure interval.

EndValue The ending value of this failure interval.

NumberInGroup The number of units that failed during this interval.

Stress() An array of numeric values or references to ALTAStressProfiles already entered into the ALTADataSet

Stress1 An numeric value or a reference to an ALTAStressProfile

Stress2 An numeric value or a reference to an ALTAStressProfile

Adds a failure interval to the collection of data points in the data set.

Usage Example

Declare the ALTADataSet. See New ALTADataSet for additional details.

       Dim ALTADS as New ALTADataSet

Declare an ALTAStressProfile. See ALTAStressProfile for additional details.

       Dim sp = New ALTAStressProfile("Profile1")
       sp.RepeatCycle = True
       sp.AddSegment(1, 250)
       sp.AddSegment(2, 300)
       sp.AddSegment(3, 400)

Add values to the raw data.

       ALTADS.AddFailureInterval(1, 5, 1, sp)
       ALTADS.AddFailureInterval(6, 10, 1, sp)
       ALTADS.AddFailureInterval(11, 15, 1, sp)
