... relation and their application to notched bar and grooved plate specimens made of four materials used in nuclear power plants without or with the effects of damage depending on stress triaxiality factor, incorporation of the effect of the Lode angle was explored for improving the consistency with the test...

... and stress triaxiality factor was introduced with an aim of predicting failure and the gradual decrease in deformation resistance. It was found that, although the predictions became more realistic, the behavior of some of the specimens could not be predicted with a sufficient accuracy when the effects...
