摘要

This paper presents the theoretical foundation for an experimental method to investigate the host-to-fibre interaction based on the remote measurement, via the optical fibre path, of the displacement 8 of the embedded fibre end relative to the surrounding host material under axial tension. It is shown that the measurement of 8 as a function of the axial strain in the host El provides key representative information on the strain transfer mechanics and the integrity of the fibre/coating/host interfaces. Parameters are defined that are based on this measurement and are directly related to familiar descriptors of strain transfer mechanics, such as failure length and interfacial shear stress.
