Calculate the critical value of mechanical potential energy

Reference no: EM131069811

In the compliance calibration of an edge-cracked fracture toughness testpiece of an aluminum alloy, it was observed that a load of 100 kN produced a displacement between the loading pins of 0.3 mm when the crack length was 24.5 mm, and 0.3025 mm when the crack length was 25.5 mm. The fracture load of an identical testpiece containing a crack of length 25.0 mm was 158 kN. Calculate the critical value of the mechanical potential energy release rate Q at fracture and hence the plane strain fracture toughness Kic of the alloy. All testpieces were 25 mm thick. For the alloy, Young's modulus, E = 70 GPa and Poisson's ratio, v = 0.3.
