摘要：

In this report a brief overview on the influence of the specimens geometry and, therefore, the stress triaxiality upon the elastic plastic fracture mechanics parameters and the stable crack extension will be given. Corresponding references to detailed publications will be given. First, possible variations of testing specimens geometries will be discussed and later the influence of stress state upon the plastic strain in case of failure will be quantitatively analysed for axialsymmetric, circumferrentially notched tensile specimens.
