Member of: SynthesisAPI.ALTADataSet

Adds a failure time to the data set.

.AddFailure(Value, NumberinGroup, Stress1)

.AddFailure(Value, NumberinGroup, Stress1, Stress2)

Parameters

Value

Required. Double. The exact time of failure.

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 ALTAStressProfile objects (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 failure times 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 failure times for Stress1 = 190 and Stress2 = 235. 
  Dim Stress(1) As Variant
  Stress(0) = 190
  Stress(1) = 235

  Call ADS.AddFailure(100, 1, Stress)
  Call ADS.AddFailure(120, 1, Stress)
  Call ADS.AddFailure(130, 1, Stress)
  Call ADS.AddFailure(140, 1, 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 failure times for Stress1 = 190 and Stress2 = 235. 
  ADS.AddFailure(100, 1, 190, 235)
  ADS.AddFailure(120, 1, 190, 235)
  ADS.AddFailure(130, 1, 190, 235)
