intermittent manual loading), loading rate, methods of detection of fiber breakage
(e.g. optical microscopy and acoustic emission).
(iv) Micro-indentation test: specimen preparation, size and shape of indenter,
methods of detecting debonding (e.g. using microscope and from the load drop in
the load-displacement curve), fiber splitting caused by indentation, methods for
data reduction (e.g. finite element model and shear-lag type analysis).
