Crack round bar test
WebConsequently in the last five years some new tests have been designed to assess for SCG behavior, as for example the Strain Hardening Test (SHT) and the Cyclic Crack Round Bar Test (CCRBT). Aside to the progress of round robin tests, these experimental procedures are currently discussed as draft standards in the ISO TC138-SC5-WG20 committee.
