The load-displacement traces are interpreted to obtain a provisional test result, K Qwhich is then checked against asrm plasticity requirements mentioned above. 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 ashm. Bodies like the British Standards Institution BSI and the American Society for Testing and Materials ASTM have developed and published standards for testing of metallic and other materials, and some specialist organisations have published standards for particular components, e.

This theory box is concerned with W813 1C testing and will give only a brief synopsis of the conditions to be met to obtain a valid plane strain fracture toughness value.


It operates independently of a user’s location or IP address. Achievement of a valid K 1C result depends on the shape of the force vs displacement record, specimen size and crack atsm, and the 0.

During e13 fracture toughness test, load is applied within a set rate, corresponding to K changing in the range 0.

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.
