ALTADataSet.AddStressProfile 10

Member of: SynthesisAPI.ALTADataSet

Other Versions: Latest

Adds an ALTAStressProfile object, which represents a time-dependent stress profile, to the data set. Applies to the cumulative damage (CD) model only.

Syntax

.AddStressProfile(Profile)

Parameters

Profile

Required. The ALTAStressProfile object.

Example

The following example demonstrates how to analyze an ALTA data set with a stress profile.

VBA

 'Declare an ALTADataSet object.  
  Dim ADS As New ALTADataSet

 'Define a stress type, with use stress = 100.  
  Call ADS.AddStressDefinition("Temperature",,100)

 'Declare a new stress profile and define its segments. 
  Dim sp As New ALTAStressProfile
   
  sp.Name = "Profile1"
  sp.RepeatCycle = True
  Call sp.AddSegment(1, 100)
  Call sp.AddSegment(2, 120)
  Call sp.AddSegment(3, 150)
 
 'Add the stress profile to the ALTADataSet object. 
  Call ADS.AddStressProfile(sp)
  
 'Add failure times to the data set. 
  Call ADS.AddFailure_2(61, 1, sp)
  Call ADS.AddFailure_2(75, 1, sp)
  Call ADS.AddFailure_2(90, 1, sp)
  Call ADS.AddFailure_2(95, 1, sp)
  Call ADS.AddFailure_2(100, 1, sp)

 'Use the cumulative damage model with the Weibull distribution. 
  ADS.AnalysisSettings.ModelType = ALTASolverModel_CumDamage
  ADS.AnalysisSettings.Distribution = ALTASolverDistribution_Weibull

 'Calculate results. 
  Call ADS.Calculate()

VB.NET

 'Declare an ALTADataSet object.  
  Dim ADS As New ALTADataSet

 'Define a stress type, with use stress = 100. 
  ADS.AddStressDefinition("Temperature",,)

 'Declare a new stress profile and define its segments. 
  Dim sp As New ALTAStressProfile("Temperature_Profile")
  sp.RepeatCycle = True
  sp.AddSegment(1, 100)
  sp.AddSegment(2, 120)
  sp.AddSegment(3, 150)
 
 'Add the stress profile to the ALTADataSet object. 
  ADS.AddStressProfile(sp)
  
 'Add failure times to the data set. 
  ADS.AddFailure(61, 1, sp)
  ADS.AddFailure(75, 1, sp)
  ADS.AddFailure(90, 1, sp)
  ADS.AddFailure(95, 1, sp)
  ADS.AddFailure(100, 1, sp)

 'Use the cumulative damage model with the Weibull distribution. 
  ADS.AnalysisSettings.ModelType = ALTASolverModel.CumDamage
  ADS.AnalysisSettings.Distribution = ALTASolverDistribution.Weibull

 'Calculate results. 
  ADS.Calculate()
