Accelerated Life Testing, formerly known as ALTA software, is an advanced module application available in ReliaSoft Weibull++ for accelerated test planning and quantitative accelerated life testing data analysis. It supports a complete array of utilities for designing accelerated life tests, evaluating the fit of the model, calculating reliability metrics, generating plots and performing related statistical analyses. Additionally, it provides the life-stress relationships required to analyze accelerated life test data with up to 8 simultaneous stress types, where stress is constant or varies with time.
Understand the effects of stresses on product life
Analyze accelerated life test data with up to 8 simultaneous stress types, where stress is constant or varies with time.
Lower development costs with improved designs
Evaluate your product performance using reliability metrics and analyses. Improve your initial designs based on accelerated life testing data in a variety of available formats and stress models.
Gain better insight with nCode GlyphWorks integration
Import and process signals or time series data from nCode GlyphWorks .s3t files and subsequently utilize the post-process profiles for reliability calculations.
Design accelerated tests to achieve desired results
Complete the most complex accelerated life testing analyses in a clear and user-friendly interface to obtain necessary metrics.
Significantly reduce test time and produce more robust designs
Predict long-term reliability metrics with minimal test time using life data from stress testing.
Provide clarity with enhanced reports and plots
Quickly provide the results, plots and reports you need to support decisions with flexible tools and automation.
