Inexpensive fracture toughness testing of welded steel
conference paper
In a prior project, TNO has presented a low-cost way of finding frac-ture toughness of base materials for cleavage fracture. That method features a small-scale CTOD specimen, combined with simplified sensors, less fatigue pre-cracking, faster testing, and no need for a temperature chamber. This meth-od has been extended to welds by considering the effect of pop-ins. This paper summarizes the prior method and the justifications for it before extending it to welded structures by introducing adjustments for pop-ins for small-scale speci-mens.
