摘要：

As a continuation of earlier-conducted investigations, a design of specimen with round, square, and triangular cross sections and an internal circular crack is proposed for determination of the crack resistance of weld joint metal for the purpose of revealing the profile most resistant to crack propagation with an equal specimen net cross-sectional area. It is concluded that the design of the specimen with the internal circular crack may imitate the operation of a weld joint material and, at the same time, there is the possibility of a quantitative evaluation of the failure resistance of the metal of a weld profile. The blind hole in the specimen serves as the chamber for addition of working media in studying their influence on the supporting capacity of the investigated profile metal. By varying the width of the groove and the outer dimensions of the specimen, it is possible to control the failure processes from brittle to ductile.
