description: This work is devoted to the study of a new local fracture criterion and an attempt to describe the phenomenon of a large-scale effect during static crack resistance testing. General concepts and problems are presented. The analysis of the existing criteria of destruction is carried out. Mechanical tests for static crack resistance of the same type of samples of the SENB type were carried out. The calculation of FEM models of samples similar to those tested mechanically was carried out. Based on the formulations given in the text of the article devoted to the new local fracture criterion, calculations were performed to predict the value of the J-integral of large samples based on the results of mechanical tests of small samples. The analysis of the obtained results is performed. A further front of work is planned to improve the ability of the new local fracture criterion to predict a large-scale effect when testing for static crack resistance.
