ABSTRACT: Five strain measurement methodologies are described and experimentally compared based on
their performance to measure axial strain of brittle matrix composite materials under uniaxial tensile loading.
A clip-on extensometer, electrical strain gages, a laser extensometer, and two Digital Image Correlation (DIC)
techniques (edge detection of a painted rectangle and speckle interferometry), ...
