In materials science, fracture toughness (KIc) refers to the ability of a material containing a crack to resist fracture. Specifically, fracture toughness testing characterizes resistance to fracture in a neutral environment with a sharp crack, and is one of the most important properties of any material for virtually all design applications. 

Fracture toughness testing is a mechanical test method used in design and fabrication to understand and prevent brittle fracture. It can also be used to determine the useful life of a material under different conditions, including fatigue, corrosion and elevated temperatures

Testing K1C Value

The KIC test (sometimes referred to as KIC, or K1C) is used to determine the fracture toughness of metallic materials. This test is in direct contrast with Charpy Impact Toughness, which can only be used to compare the notch toughness of materials or determine a metal’s compliance with a specification. Most often associated with ASTM E399, the Linear-Elastic Plane Strain Fracture Toughness test (or KIc value) can be used as a direct measurement across a range of temperatures to determine design, life calculations and crack growth, or remaining life calculations.

CTOD Testing

Crack Tip Opening Displacement, or CTOD, is a measure of the physical opening of the fatigue crack tip at the point of failure. CTOD testing measures the toughness of materials that tear before failure, and provides a single value at the first sign of instability.

Testing J1C and JR Values

J-based fracture toughness testing measures the energy released during crack extension. This method is used to evaluate materials with high toughness and low strength measurements.
