Application:

The tester measuring fracture toughness of rock material, fracture toughness is mainly based on the Angle of the crack propagation resistance classifying and on the intact rock, other purposes is checking the index of rock breaking process (Shield Tunneling Under Crushed) and hydraulic fracturing blasting crack and stability analysis.
