Retardation of Fatigue Crack Growth in Rotating Bending Specimens with Semi-Elliptical Cracks [PDF]
Metals, 2019 This work investigates overload-induced retardation effects for semi-elliptically cracked steel round bars. The specimen geometry equals the shaft area of a 1:3 down-scaled railway axle and the material is extracted from railway axle blanks made of EA4T ...

On the Cyclic J-Integral of a 3D Semi Elliptical Surface Crack [PDF]
Volume 5: High-Pressure Technology; ASME NDE Division; 22nd Scavuzzo Student Paper Symposium and Competition, 2014 This paper investigates an approach for calculating the cyclic J-Integral (ΔJ) through a new industrial application. A previously proposed method is investigated further with the extension of this technique through a new application of a practical 3D notched component containing a semi-elliptical surface crack.

Constraint Assessment for Cruciform Specimens With a Semi-Elliptical Crack [PDF]
Volume 6A: Materials and Fabrication, 2018 A real crack to be assessed in a RPV is generally a shallow crack subjected to biaxial far-field stresses. However, the fracture toughness Kc or Jc, which is an important material property for the structural integrity assessment of RPV containing cracks, are usually tested on deep cracked compact tension [C(T)] or single-edged bending [SE(B)] specimens
