Abstract

This research presents an experimental Evaluation of J-Integral for Fiber Reinforced Concrete Subjected to Impact Loading. Three-point edge notched bend specimen were employed in evaluation of J-Integral using both the multi-specimen, and the single specimen techniques. In the multi-specimen technique three different notch lengths were employed for extracting the energetic fracture parameter J_Ic. In the single specimen technique, the method developed by Rice[13] was used to evaluate J_Ic at three different notch lengths.

Different proportions of fiber were employed in determining the J_Ic values. Experimental results from present study indicates that the J_Ic values calculated for the same fiber content at different crack lengths are similar.
