| Summary: | This paper presents the results of experimental and numerical analysis of fracture mechanics testing of ductile metallic materials using a non-standard procedure with PRNT (pipe ring notched tensile) ring-shaped specimens, introduced in previous publications through analysis of 3D-printed polymer rings. The main focus of this research is the determination of the values of the plastic geometry factor <i>η<sub>pl</sub></i> since the specimen is not a standard one. Toward this aim, the finite element software package Simulia Abaqus was applied to evaluate the <i>J</i>-integral (by using the domain integral method) and the <i>F</i>-CMOD curve so that the plastic geometry factor <i>η<sub>pl</sub></i> can be evaluated for different values of the ratio of crack length to specimen width (<i>a</i><sub>0</sub><i>/W</i> = 0.45 ÷ 0.55). In this way, a procedure and the possibility of practical implementation on the thin-walled pipelines are established. |
