Instantiate this class to be able to fit an ALTA model from your raw data.

Constructors

  • New ALTADataSet Creates a new class that can be used to fit a model from ALTA raw data.

Methods

  • AddStressDefinition Adds a stress definition (column). The number of stresses in subsequent calls to AddFailure, AddSuspension etc. must be equal to the number of stress definitions in the data set.
  • AddStressProfile Adds a stress profile to the data set. It then can be used as a stress for Cumulative Damage model.
  • AddFailure Adds a failure data point to the collection of data points in the data set.
  • AddSuspension Adds a suspension data point to the collection of data points in the data set.
  • AddFailureInterval Adds a failure interval data point to the collection of data points in the data set.
  • AddSuspensionInterval Adds a suspension interval data point to the collection of data points in the data set.
  • Calculate Fits a model from the raw data previously entered in the data set. Sets FittedModel property if successful. Clears it (sets to Nothing) in case of an error.
  • ClearDataSet Clears all data and fitted model. All analysis settings stay unchanged.

Properties

  • DatasetName Gets or set the name of the data set.
  • GeneralSettings General settings used when fitting the model or finding the best fit.
  • AnalysisSettings Settings used when fitting the model.
  • FittedModel Model, fitted from the raw data. See cModel class for the list of its methods below.
  • FailureCount Total number of failures in the data set.
  • SuspensionCount Total number of suspensions in the data set.
  • NumStresses Returns the number of stresses in the data set.
  • StressRelation Sets or returns life-stress relationship for a particular stress.
  • PlotUseStress Sets or returns use stress value for a particular stress. This value is used in subsequent plotting of the data set.
  • AnalysisResults Returns an instance of a class containing values calculated during the analysis.

Events

  • Events Reference to a class that contains overridable methods for handling ALTA solver events
