Sažetak:
Through the time, researches realize the problem of inability to measure the fracture tough-ness of pipe material, because of inability of producing standard specimens from pipe wall. This problem is especially expressed in thin walled pipes. In that sense, a lot of alternative procedures and nonstandard specimens are proposed. One of latest and the most conven-ient one is Pipe Ring Notched Bend specimen (PRNB) proposed by Gubeljak and Matvienko which is also patented by mentioned authors. Research within this paper deals with effect of stress triaxiality on the PRNB specimens in two states, with and without influence of residual stresses (RS). Four different pipes are considered, all produced according to the EN 10216 standard, so hot rolled seamless pipes, produced from material 16Mo3.
