MODELING OF STRESS-CRACK WIDTH RELATIONSHIP OF HIGH PERFORMANCE FIBER REINFORCED MORTAR UNDER UNIAXIAL TENSILE LOADING

In this study, influence of fiber orientation on tensile behavior of High Performance Fiber Reinforced Mortar (HPFRM) was examined. A stress-crack width model has been proposed which can consider the influence of fiber orientation. The parameters in this study are volume of fiber and fiber orientation by the direction of flow at casting. Based on experimental results, the model parameters were empirically formulated. By probabilistic approach...
