Weibull Analysis of Textile Failure Data
topic
Weibull analysis fits a two or three parameter Weibull distribution to textile tensile strength, fatigue life, or abrasion failure cycle data using maximum likelihood estimation, graphical probability plotting, and Anderson-Darling goodness of fit testing; shape parameter beta characterises failure rate behaviour as decreasing, constant, or increasing while scale parameter eta represents the characteristic life at 63.2 percent failure probability.
Role
Provides the most widely applicable probabilistic failure analysis framework for textile material strength and durability data, enabling calculation of minimum strength guarantees at defined confidence levels, comparison of material reliability between fibre types and constructions, and identification of mixed failure mode populations indicating heterogeneous material quality.
