Abstract

Accurate strain measurement for single fibers is critical for many engineering applications. Typically, the crosshead displacement is used to calculate strain when performing mechanical testing, however there are complicating factors: slack in the specimen or slipping/seating in the grips, compliance of the load frame, and grip effects. These are addressed in various testing standards for single fibers, such as ASTM Standards D3822 and C1557. In this work, an analysis has been performed to examine both ASTM Standard D3822 and ASTM Standard C1557 to evaluate the utility of these standards for strain correction. This analysis indicates that while the standards provide valuable instructions for performing tensile testing, the suggested methods for strain correction are not supported.
