Advanced Engineering Materials, Volume 27, Issue 6, March 2025.The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

AIMS MathematicsIn this paper, we investigate a von Karman plate system with general type of relaxation functions on the boundary. We derive the general decay rate result without requiring the assumption that the initial value $ w_0 \equiv 0 $ on the boundary, using the

On the relaxation of nonconvex superficial integral functionals
Journal de Mathématiques Pures et Appliquées, 2000 We present a new approach to the variational relaxation of functionals $F:D(\mathbb{R}^N;\mathbb{R}^m)\to[0,\infty[$ of the type:$$F(v):=\int_{\mathbb{R}^N}W(\nabla v(x))d\mu(x),$$where $W:\mathbb{R}^{mN}\to[0,\infty[$ is a continuous function with growth conditions of order $p\geq 1$ but not necessarily convex. We essentially study the case when $\mu$

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 ...

Creep and relaxation responses of fly ash concrete: Linear and nonlinear cases
Case Studies in Construction Materials, 2022 The application of reinforced concrete has been used in various engineering and architecture fields. Stress relaxation and creep are two crucial time-dependent behaviours of concrete. The influence of two behaviours is closely related to the service life

Advanced Engineering Materials, EarlyView.In this study, the mechanical response of Y‐shaped core sandwich beams under compressive loading is investigated, using deep feed‐forward neural networks (DFNNs) for predictive modeling. The DFNN model accurately captures stress–strain behavior, influenced by design parameters and loading rates.
