A Numerical Study of the Effect of Isotropic Hardening Parameters on Mode I Fatigue Crack Growth
Metals, 2020 The consideration of plastic crack tip opening displacement (CTOD, δp), as a crack driving force has given us the opportunity to predict fatigue crack growth (FCG) rate numerically, and, therefore, to develop parametric studies focused on the effect

Elastic-plastic defect interaction in (a)symmetrical double edge notched tension specimens [PDF]
, 2017 Interaction of defects tends to intensify their crack driving force response compared to the situation where these defects act independently. The interaction between multiple defects is addressed in engineering critical assessment standards like BS7910 ...

Study of SENT specimens with a tilted notch to evaluate ductile tearing in spiral welded pipeline applications [PDF]
, 2015 There is an increasing interest for the use of spiral welded pipelines in strain based design applications. Environmentally imposed loads are able to plastically deform the pipelines, meaning that their structural response is of the utmost importance ...

International Journal of Applied Mechanics and Engineering, 2017 This paper provides a numerical analysis of selected parameters of fracture mechanics for double-edge notched specimens in tension, DEN(T), under plane strain conditions. The analysis was performed using the elastic-plastic material model.

Implementation of Recent Advances in Fracture Toughness Testing to Investigate Tearing Resistance of Heat-Resistant Steel 14MoV6-3 [PDF]
Archives of Metallurgy and MaterialsSince WWII, progress has been made in understanding how materials fail and how to prevent such failures. In this work, the newly standardized Single Edge Notch Tension (SENT) specimen is used to assess the ductile tearing resistance of 14MoV-3 steel ...

The Effect of Notch Depth on CTOD Values in Fracture Tests of Structural Steel Elements
Polish Maritime Research, 2018 In elements of steel structures working at low temperatures, there is a risk of appearance of brittle fracture. This risk is reduced through the use of certified materials having guaranteed strength at a given temperature.
