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. The stress values, where Stress(0) = value for first stress definition, Stress(1) = value for second stress definitition, etc. Can be an array of numeric stress values or ALTAStressProfile objects (stress profiles apply to the cumulative damage (CD) model only).

Stress1

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

Stress2

Required. Object. The stress value for the second stress definition. 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 a stress type with use stress level = 10. 
  Call ADS.AddStressDefinition("Stress1",,10)
   
 'Add 2 interval censored data points for Stress1 = 190. 
 'The failures occurred between time = 10 and time = 20. 
  Dim Stress(0) As Variant
  Stress(0) = 190 

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

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