Summary:Title screen
General regularities on the influence of the stress concentrator shape onto fracture toughness of 17Mn1Si steel used for the construction of main gas pipelines are established. The energy consumption of initiation and propagation of the main crack are measured. An approach based on using the shape of shear lips as an informative fractodiagnostic feature is developed. It is shown that specimens with V - shaped concentrator have shear lips of a rounded shape, while specimens with I - shaped one have more “straight” shear lips. Specimens with U - shaped notches have elongated shear lips with focal tears-out of the material.
