Revision as of 19:06, 15 April 2016

Adds a stress definition to the data set.

Syntax

.AddStressDefinition(Name, StressRelation, UseStress)

Parameters

Name

Required. String. The name of the stress.

StressRelation

Optional. The stress transformation that will be applied to the stress. Can be any ALTASolverLSR constant. Default value = 0.

UseStress

Optional. Double. The use stress level. Default value = 1.

Example

The following example demonstrates how to add stress definitions 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)

-{{Template:ALTADataSet.AddStressDefinition.Cmt}} The number of stress values used in subsequent calls to AddFailure, AddSuspension, etc. must be equal to the number of stress definitions in the data set (e.g., before you can add a failure time obtained with two stresses, you must add two stress definitions).
