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

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.
