Evaluation of Coatings by Spectrochemical and Electrochemical Analyses. Sign in or create your free personal ASME account. In case 1, fracture occurs with no previous significant plasticity, in case 2 some plasticity occurs prior to fracture, while in case 3 a pop-in occurs, followed by some plasticity prior to final fracture.
This is done because the J-integral test excludes certain geometries.
Achievement of a valid K 1C result depends on the shape of the force vs displacement record, specimen size and crack geometry, and the 0.

The load-displacement traces are interpreted to obtain a provisional test result, K Qaastm is then checked against the plasticity requirements mentioned above. Hence certain conditions have to be met in the tests regarding specimen and crack e183, loading parameters and shape of load-displacement curve, before a valid result can be reported.
