CTOD Testing

(Services offered through our parent company)

Fracture Toughness determines the amount of stress required to propagate an existing flaw or defect in specific materials. Since traditional methods of destructive testing cannot always predict how a material will behave with a defect, fracture toughness is very important in the design stage.

Crack-Tip Opening Displacement (CTOD) is used as a type of fracture toughness testing to determine if a material is appropriate for strenuous working conditions. CTOD testing is the measure of plastic deformation prior to failure in a pre-cracked sample. This type of test is a variation of fatigue testing that has load rates more representative of in-service conditions.
