It operates independently of a user’s location or IP address. In both cases, after completing the test, the data is examined to see if it will provide a valid K 1C value. It replaces the multiple user names and passwords necessary to access subscription-based content with a single user name and password that can be entered once per session.
During the fracture toughness test, load is applied within a set rate, corresponding to K changing in the range 0.
If not, one then has the option of determining a yielding fracture mechanics parameter. 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.
