چکیده انگلیسی
Analysis of the data obtained for the two slower loading rates that exhibited ductile fracture throughout the entire growth process shows that the energy release rate Gcdâ¯=â¯70â¯J/m2, and the final separation, δcdâ¯=â¯250â¯Âµm for the slowest loading rate of 0.03â¯mm/min and, Gcdâ¯=â¯120â¯J/m2, and the final separation, δcdâ¯=â¯250â¯Âµm for 0.3â¯mm/min loading rate. For the highest loading rate, which exhibited nominally brittle fracture, the energy release rate Gcbâ¯=â¯10â¯J/m2, and the final separation δcdâ¯=â¯1.5â¯Âµm. The peak cohesive stresses during ductile and brittle fracture are determined to be Ïdâ¯=â¯0.7â¯MPa and Ïbâ¯=â¯9.6â¯MPa, respectively, for loading rates of 0.3â¯mm/min and 3â¯mm/min, respectively. Finally, COD at the onset of crack growth measured at 1.00â¯mm behind the moving crack tip for the loading rate of 0.3â¯mm/min, CODdâ¯ââ¯0.30â¯mm, remaining constant for crack lengths, a, in the range 25â¯mmâ¯â¤â¯aâ¯â¤â¯165â¯mm.
