Abstract: The computation of a Load Factor, a Life Factor or a Load Enhancement Factor using Modified Joint Weibull Analysis may include retrieving a test data set from at least one database and analyzing the data retrieved for fit with a Weibull distribution model. The test data may be analyzed to determine if at least two coupons have been tested and if applied loads and duration of testing at a component-level were varied. A shape parameter may be calculated for the Weibull distribution model. A scale parameter may be calculated for the Weibull distribution of the data. A stress to life cycle relationship may be calculated to account for scatter in the data through the Weibull distribution data. The Life Factor, the Load Factor or the Load Enhancement Factor may be calculated based on the stress to life cycle relationship to account for scatter.

Abstract: The computation of a Load Factor, a Life Factor or a Load Enhancement Factor using Modified Joint Weibull Analysis may include retrieving a test data set from at least one database and analyzing the data retrieved for fit with a Weibull distribution model for the data. The test data may be analyzed to determine if at least two coupons have been tested and if both the applied loads and duration of testing at the component-level were varied. At least one shape parameter may be calculated for the Weibull distribution model after which the shape parameter may be stored. At least one scale parameter may be calculated for the Weibull distribution of the data after which the scale parameter may be stored. A stress to life cycle relationship may also be calculated to account for scatter in the data through the Weibull distribution data.

Abstract: A method and computer system for executing a program for calculating Load Enhancement Factor that includes the steps of obtaining coupon test data and storing the coupon test data on an information storage device. Analyzing the coupon test data for fit with a Weibull distribution and other analysis criteria and performing either a Modified Joint Weibull analysis or a Weibull Regression analysis or both a Modified Joint Weibull analysis and a Weibull Regression analysis with an accommodation in the analysis for scatter within the coupon testing data.
