Abstract

A simple analytical model is developed for the evaluation of the bending stress caused by the misalignment of the ends of a glass fiber specimen soldered into a ferrule and subjected to tension during pull testing. It is shown that this stress can be reduced by use of sufficiently long specimens. It is also shown how the uncertainty in the prediction of the misalignment of the ends can be considered when one is establishing the appropriate specimen length.
