Fracture toughness is an indication of the amount of stress required to propagate a preexisting flaw. It is a very important material property since the occurrence of flaws is not completely avoidable in the processing, fabrication, or service of a material/component.

Fracture toughness is indicated by the area below the curve on strain-stress diagram (see the figure): ... Stress-intensity Factor (K) is a quantitative parameter of fracture toughness determining a maximum value of stress which may be applied to a specimen containing a crack (notch) of a certain length.

Another type of test used to determine crack propagation resistance is usually referred to as a 'plane strain' fracture toughness test. This test evaluates the ability of a material to prevent crack growth while being subjected to an increasing load rather than a cyclic load.
