ASTM E is a test method used to analyze the fracture toughness of a material by measuring the crack-tip opening displacement in materials that exhibit. Since the British Standards Institution (BSI) standardized BS in , a popular way of calculating the Crack Tip Opening Displacement. ASTM E is a test method that covers the determination of critical crack-tip opening displacement (CTOD) values at one or more of several crack extension.

Superficial surface machining may be used when desired.
The three events in which CTOD measurements are e120 include; a the onset of unstable crack extension without significant prior stable crack extension, b onset of unstable crack extension with significant prior stable crack extension, or c the end-of-test after significant slow stable crack extension. It operates independently of a user’s location or IP address.
This test method covers the determination of critical crack-tip opening displacement CTOD values at one or more of several crack extension events, and may be used to measure cleavage crack initiation toughness for materials that exhibit a change from ductile to brittle behavior with decreasing temperature, such as ferritic steels.
This test method may be used to characterize the toughness of materials for which the properties and thickness of interest preclude the determination of K lc fracture toughness in accordance with Test Method Eallowing the use of sub-sized specimens to estimate K Ic.

Testing Procedure ASTM considers three fracture events to be important to the fracture toughness of a material. The specimens are tested under crosshead or clip gage displacement controlled loading. A bending test, with slow bending rates, will be used to propagate the fracture.
