Abstract
Tensile fracture in portland cement based fiber composites is studied. Formation and propagation of stable microcracks is examined by means of holographic interferometry. Distributed microcracking beyond the matrix ultimate tensile strength is studied using quantitative optical microscopy. Using an effective traction-free critical crack approach and superposition of the closing pressure due to fiber pull-out response, an R-curve formulation is obtained. The theoretical model is compared with the experimental results.
