Gradient approach for the evaluation of the fatigue limit of welded structures under complex loading [PDF]
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.

Evaluation of extremely steep residual stress gradients based on a combined approach using laboratory-scale equipment [PDF]
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.

Stress Gradient Effects on Notched Composite Failure Using a Local-Global Approach [PDF]
Micromechanics based analysis to predict damage initiation in compressively loaded symmetric notched multidirectional laminates under remote uniaxial loading is described. A novel hybrid local-global finite element method in conjunction with the commercial code ABAQUS is used to solve the governing system of equations.
