Mobasher, A. Castro-Montero, S. Shah] Micromechanisms of matrix fracture in Portland cement-based fiber composites were studied by means of reflection holographic interferometry and quantitative image analysis. An experimental investigation was conducted with different volume concentrations of polypropylene fibers. Uniaxial tensile specimens were loaded within a strain range of up to three percent. The deformation history was recorded as interference holograms. The holograms were acquired in an image-analysis system. After enhancement, they were analyzed for crack density, length, opening profile, and spacing. The evolution of microcracks, their propagation, distributed microcracking and the material response beyond the characteristic damage state are also discussed.
