Latest revision as of 20:41, 24 June 2016

Adds a stress type 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. Applies to the general log-linear (GLL) or cumulative damage (CD) models only. Can be any ALTASolverLSR constant. Default value = 0 (exponential life-stress relationship).

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. 
  Call ADS.AddFailure_3(100, 1, 190, 235)
  Call ADS.AddFailure_3(120, 1, 190, 235)
  Call ADS.AddFailure_3(130, 1, 190, 235)

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)
