The load-displacement traces are interpreted to obtain a provisional test result, K Qwhich is then checked against the plasticity requirements mentioned above. Some tools below are only available to our subscribers or users with an online account. In both cases, after completing the test, the data is examined to see if it will provide a valid K 1C value.

If this is not the case, it is possible that there was too much plasticity prior to the fracture occurring and a CTOD analysis should be performed.
