Influence of the stress gradient on the fatigue life calculation of a martensitic high strength steel [PDF]
Fracture and Structural Integrity, 2017 Nowadays lifetime calculation in the high cycle fatigue region is commonly based on S/N curves which are modified by different influences to ensure accurate results.

Numerical approach for a continuum theory with higher stress gradients [PDF]
PAMM, 2021 AbstractWe use an extended balance of linear momentum derived from stress field analysis of higher order terms in power series expansion. Thus, the balance equation accounts for higher gradients of stress in the contiguity of continuum points. Interestingly, it does not coincide with the balance of linear momentum from strain gradient elasticity.

Vertical Stress Prediction for Zubair Oil Field/ Case Study
Journal of Engineering, 2023 Predicting vertical stress was indeed useful for controlling geomechanical issues since it allowed for the computation of pore pressure for the formation and the classification of fault regimes.

Gradient approach for the evaluation of the fatigue limit of welded structures under complex loading [PDF]
Fracture and Structural Integrity, 2017 Welded ‘T-junctions’ are tested at different load ratio for constant and variable amplitude loading. Fatigue results are analyzed through the type of fatigue mechanisms depending on the loading type.

Nonlinear flexure mechanics of beams: stress gradient and nonlocal integral theory
Materials Research Express, 2021 In order to study the intrinsic size-effects, the stress gradient theory is implemented to a nano-scale beam model in nonlinear flexure. The nonlocal integral elasticity model is considered as a suitable counterpart to examine the softening behavior of ...

Evaluation of extremely steep residual stress gradients based on a combined approach using laboratory-scale equipment [PDF]
Journal of Applied Crystallography, 2021 Surface treatments characterized by rapid heating and cooling (e.g. laser hardening) can induce very steep residual stress gradients in the direct vicinity of the area being treated. These gradients cannot be characterized with sufficient accuracy by means of the classical sin2Ψ approach applying angle-dispersive X-ray diffraction.
