Fig. 6. Time-domain response of FCR as a function of strain for LBM specimens: (a) without fillers; b) without fillers at the first 100s of test (c) with 1.0% CNT, d) with 1.0% CNT at the first 100s of test, and (e) with 0.5% CCMF. DIC analysis was conducted to capture strain development during the three-point bending test for each sample. Fig. 7 presents a visual representation of the crack observed during the test.
