The results differ from the classical fracture mechanics in that the stresses around the crack tip are finite by using the non-local elasticity, but they are infinite in the classical fracture mechanics. The present calculated results coincide with Eringen's [1] but our model and calculation process is much simpler. At the same time, the maximum tensile stress of the crack tip and fracture toughness are in close agreement with the original experimental results.
