Since the British Standards Institution (BSI) standardized BS in , a popular way of calculating the Crack Tip Opening Displacement (CTOD) has been. ASTM E “Crack-Tip Opening Displacement (CTOD) Fracture. Toughness Measurement”. These standards give a method for determining critical crack tip. ASTM E previously used the plastic hinge model for the calculation of CTOD , but has changed its CTOD calculation to J-based conversion since

These CTOD values can be used as measures of fracture toughness for metallic materials, and are especially appropriate to materials that exhibit a change from ductile to brittle behavior with decreasing temperature. The specimens are tested under crosshead or clip gage displacement controlled loading.

Testing Procedure ASTM considers three fracture events to be important to the fracture toughness of a material. ASTM E is a test method used to analyze the fracture toughness of a material by measuring the crack-tip opening e190 in materials that exhibit change from ductile to brittle behavior with decreasing temperature.
