ALTADataSet.AddFailureInterval

Member of: SynthesisAPI.ALTADataSet

Adds interval censored failures to the data set.

Syntax

.AddFailureInterval(StartValue, EndValue, NumberinGroup, ByRef Stress())

.AddFailureInterval(StartValue, EndValue, NumberinGroup, Stress1)

.AddFailureInterval(StartValue, EndValue, NumberinGroup, Stress1, Stress2)

Parameters

StartValue

Required. Double. The starting value of the failure interval.

EndValue

Required. Double. The ending value of the failure interval.

NumberinGroup

Required. Integer. The number of failed units at the time of failure.

Stress()

Required. Object. Can be an array of numeric stress values or an ALTAStressProfile object (stress profiles apply to the cumulative damage (CD) model only).

Stress1

Required. Object. Can be a numeric stress value or an ALTAStressProfile object (stress profiles apply to the cumulative damage (CD) model only).

Stress2

Required. Object. Can be a numeric stress value or an ALTAStressProfile object (stress profiles apply to the cumulative damage (CD) model only).

Example

The following example demonstrates how to add interval censored failures to an ALTADataSet object.

VBA

 'Declare a new ALTADataSet object.  
  Dim ADS As New ALTADataSet
 
 'Define 2 stress types with use stress levels = 10 and 25. 
  Call ADS.AddStressDefinition("Stress1",,10)
  Call ADS.AddStressDefinition("Stress2",,25)
  
 'Add 2 interval censored data points for Stress1 = 190 and Stress2 = 235. 
 'The failures occurred between time = 10 and time = 20. 
  Dim Stress(1) As Variant
  Stress(0) = 190 
  Stress(1) = 235

  Call ADS.AddFailureInterval(10, 20, 2, Stress) 

VB.NET
 
 'Declare a new ALTADataSet object.  
  Dim ADS As New ALTADataSet
 
 'Define 2 stress types with use stress levels = 10 and 25. 
  ADS.AddStressDefinition("Stress1",,10)
  ADS.AddStressDefinition("Stress2",,25)
 
 'Add 2 interval censored data points for Stress1 = 190 and Stress2 = 235. 
 'The failures occurred between time = 10 and time = 20. 
  ADS.AddFailureInterval(10, 20, 2, 190, 235)
