Understanding CTOD Testing
Qualitest Canada performs CTOD Testing Services in Halifax Canada for various clients around the world. CTOD (Crack Tip Opening Displacement) is a fracture-toughness test method used to determine the resistance of metallic materials—particularly steels and welds—to crack propagation under stress. The test measures the amount of deformation (opening displacement) that occurs at the tip of a crack before fracture.
This parameter is critical for evaluating structural integrity in welded joints, pipeline steels, offshore platforms, pressure vessels, and other high-stress components operating in demanding environments.
Common standards include:
- BS 7448 Part 1 & 2 – Fracture toughness (CTOD) testing
- ASTM E1820 / E1290 – Measurement of fracture toughness (J-integral, CTOD)
- ISO 12135 – Metallic materials – Unified method for fracture toughness
