The estimation of the tensile strength of certain brittle fibers at extremely short lengths from tensile strength measurements of these fibers at longer lengths is of fundamental importance in the theory of modern fiber composite materials. We examine a competing risks model in which the fiber strength arises as the minimum of two (independent) Weibull random variables having distinct Weibull e...
