Identification of Factors Affecting Single Filament Pull-Out Test Results



In this paper, computer generated plots of pull-out load Pm versus embedded length l are used to identify important factors influencing the experimental results obtained in the single filament pull-out test. The computer results suggest that random variation in the initial crack size is an important source of scatter in the experimental data. Furthermore, variation in fiber surface energy was computed to play a much smaller role than crack size variation in producing the observed data scatter. The results also suggest that the initial crack size corresponding to observed pull-out loads is surprisingly large. Finally, residual stress detrimental to the interfacial bond was identified as the factor causing an apparent displacement of the data points to the right, as observed experimentally.
