Accelerated Life Testing module
Accelerated test data analysis and test plans for multiple stresses and constant or time varying stress profiles
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.
