Mapping the gender gradient in posttraumatic stress disorder prevalence: A machine learning approach

Journal of Traumatic Stress
AbstractThe prevalence of posttraumatic stress disorder (PTSD) among women is over twice that of men, but the underlying mechanisms for these differences remain poorly understood. This study introduces a novel approach to examining gender and PTSD, moving beyond the binary group labels of male and female to explore the summative impact of gender‐linked

The strain gradient approach for determination of forming limit stress and strain diagrams

Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2008
The forming limit stress diagram (FLSD) has been reported as being much less path dependent and much more favourable than the forming limit diagram (FLD) in representing forming limits in the numerical simulation of sheet metal forming processes. Therefore, the purpose of this study was to develop a methodology for the prediction of the forming limits

X-ray diffraction at constant penetration depth – a viable approach for characterizing steep residual stress gradients

Journal of Applied Crystallography, 2008
The experimental analysis of near-surface residual stresses by X-ray diffraction methods is based on measuring the spacings of lattice planes while the inclination ψ with respect to the surface plane is changed stepwise. A characteristic feature of conventional techniques is that the penetration depth of the X-rays is altered as inclination is varied ...

A Non Local Multiaxial Fatigue Approach to Account for Stress Gradient Effect Applied to Crack Initiation in Fretting

Journal of ASTM International, 2010
Abstract Although fatigue limits of smooth specimens under various complex loadings have been determined, few models have been proposed to predict well-known experimental results such as size effects and stress gradient effects. This paper addresses the stress gradient effect issue. A new non local multiaxial fatigue approach is proposed

Stress gradient effects on magnetic eigenmodes in ferromagnetic nanobars: a micromagnetic approach to magnetoelastic coupling

Journal of Physics D: Applied Physics
Abstract We demonstrate deterministic control of magnetic eigenmodes in ferromagnetic nanobars through engineered stress gradients. By combining finite-element mechanical modeling with micromagnetic simulations, we show how bending-induced strain fields alter both static magnetization configurations and dynamic ...

Study of component structural equivalent fatigue based on a combined stress gradient approach and the theory of critical distance

Engineering Failure Analysis, 2015
Abstract Fatigue limit load is one of the most important factors and concerns in designing and manufacturing critical mechanical parts such as crankshafts. Traditionally, this governing parameter is obtained via a time and money-consuming experiment and analysis of a simple structure while it becomes theoretically complicated for sophisticated cases.

Non-local stress gradient approach for multiaxial fatigue of defective material

Computational Materials Science, 2008
Abstract The fatigue crack initiation from a surface defect is analysed by means of a new attempt based on multiscale reduction of the stress distribution along the potential crack initiation plane. The reduction is performed by averaging process for shear and normal stresses over two critical areas (multiscale concept). The Matake multiaxial fatigue
