Re: [MW:23150] CTOD AND CHARPY TEST

Charpy test is type of test to measure the resistance of a material to shock type stresses whether in room or minus temperatures. 

CTOD (Crack Tip Opening Displacement) is for measuring the resistance of material to cyclic type of stresses whether in room or minus temperatures.

So the main difference is the type of load which used during the test. So the specimens preparation and test procedures are different.
