Simulation of Inhomogeneous Refractive Index Fields Induced by Hot Tailored Forming Components

Advanced Engineering Materials, EarlyView.
This article presents a simulation model for simulating inhomogeneous refractive index fields (IRIF) in hot‐forged components, accounting for thermal influences and complex geometries. Through this simulation, a priori knowledge about the propagation of the IRIF can be obtained, allowing for the positioning of the component or an optical measurement ...

Fully nonlinear degenerate equations with applications to Grad equations

Electronic Journal of Qualitative Theory of Differential Equations
We consider a class of degenerate elliptic fully nonlinear equations with applications to Grad equations: \begin{align*} \begin{cases} |Du|^\gamma \mathcal{M}_{\lambda,\Lambda}^+\big(D^2u(x)\big)=f\big(|u\geq u(x)|\big) &\text{ in }\Omega\\ u=g ...

Impact of Iron Contamination on Liquid Properties and Microstructural Evolution in AlSi20

Advanced Engineering Materials, EarlyView.
Recycled aluminum is much more energy conservative and sustainable than primary aluminum. However, the iron contamination in secondary aluminum is vastly responsible for the degradation of the material properties. Herein, it is aimed to evaluate the influence of iron contamination in hypereutectic Al–Si alloy through thermodynamic as well as ...

The performance of 1% solution of baking soda as the mouthwashing for elderly xerostomia patients on the salivary secretion

Padjadjaran Journal of Dentistry, 2018
Introduction: The ageing process in older adults could cause a decreasing salivary secretion. Indicators of salivary secretion could be measured by observing an increasing salivary volume and pH, and a decreasing salivary viscosity.

Comparative Wear and Friction Analysis of Sliding Surface Materials for Hydrostatic Bearing under Oil Supply Failure Conditions

Advanced Engineering Materials, EarlyView.
Hydrostatic bearings excel in high‐precision applications, but their performance hinges on a continuous external supply. This study evaluates various material combinations for sliding surfaces to mitigate damage during supply failures or misalignment and to discover the most effective materials identified for enhancing the reliability and efficiency of

Trans‐Conductive Melt Pool Scaling and its Implications for Parameter Transfer in Laser Powder Bed Fusion for Metals with High Thermal Diffusivity

Advanced Engineering Materials, EarlyView.
Developing process parameters for the laser‐based Powder Bed Fusion of metals can be a tedious task. Based on melt pool depth, the process parameters are transferable to different laser scan speeds. For this, understanding the melt pool scaling behavior is essential, particularly for materials with high thermal diffusivity, as a change in scaling ...

Convergence to a viscosity solution for an advection-reaction-diffusion equation arising from a chemotaxis-growth model

, 1999
. We study the limiting behavior as ε tends to zero of the solution of a Cauchy problem for an advection-reaction-diffusion equation; this equation arises in a model for a chemotaxis growth process in biology.
