Purpose of CTOD Testing
Applied Technical Services offers CTOD testing for companies who need to determine the suitability of their design materials. Various factors can lead to the initiation of a crack in a structural material, including welding imperfections, stress corrosion, material fatigue, and improper use, to name a few. Once formed, these imperfections propagate to the point of complete fracture if left untreated. Manufacturers and fabricators favor structural materials that display a greater fracture toughness for this reason.
