A simplified micromechanical model of compressive strength of fiber-reinforced cementitious composites

A micromechanical model is constructed for the compressive strength of fiber-reinforced cementitious composites (FRCs). This model is based on the classical models of compressive failure of brittle soilds in which sliding microcracks induce wing-crack growth under compression loads. The concept of increased microcrack sliding resistance and wing-crack growth retardation associated with fiber bridging is exploited to produce a strengthening...
