Abstract
The CTOD-design curve contains an internal safety factor, but the exact value of the factor has not been previously known. Experimental safety factors are the product of the internal safety factor and an external safety factor from the CTOD test results themselves. Here, the CTOD-design curve safety factor is determined based on a theoretical statistical treatment of experimental data.
Presently only a few crude rules exist for the assessment of HAZ fracture toughness. They are all based on a microstructural validation of each specimen after the test. Because of difficulty to obtain valid results many tests are performed in vain. New, more efficient guidelines for performing CTOD testing of HAZ with respect to assessment of local brittle zones are given, based on statistical modelling.
