| Abstract: | In this study, edge cracked sheet specimens made from polybutadiene rubber embedded with hard particles were used in crack
propagation tests. Crack propagation tests were conducted under two crosshead speeds (2.54 mm/min and 12.7 mm/min) at three
temperatures (−53.9°C, 22.2°C and 73.9°C). The experimental data were analyzed and the crack growth resistance curves and
the crack growth rate versus the Mode I stress intensity factor were plotted. Based on these experimental results, the effects
of temperature and loading rate on the crack growth behavior were investigated and the results are discussed. |
