Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

Advanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Variable Stiffness Flexure Structures Enabled by Phase‐Change Gallium and Adhesive Interfacial Locking for Soft Robotic Applications

Advanced Engineering Materials, EarlyView.
A flexure‐based variable stiffness structure is developed by integrating phase‐change modulation and adhesive interfacial locking of gallium. The design enables a wide stiffness variability, transitioning from soft, flexible behavior to rigid, load‐supporting performance.

Positive radial solutions for systems with mean curvature operator in Minkowski space [PDF]

, 2017
We are concerned with a Dirichlet system, involving the mean curvature operator in Minkowski space M(w) = div (∇w / 1−|∇w|2) in a ball in RN. Using topological degree arguments, critical point theory and lower and upper solutions method, we obtain non ...

Karl Popper and the Mechanisms of Hydrogen Embrittlement

Advanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Positive solutions for a class of quasilinear singular equations

Electronic Journal of Differential Equations, 2004
This article concerns the existence and uniqueness of solutions to the quasilinear equation $$ -Delta_p u= ho(x) f(u) quad hbox{in } mathbb{R}^N $$ with $u > 0$ and $u(x)o 0$ as $|x| o infty$.

Understanding the Stochastic Nature of Process Parameter Development of Blown Powder Laser Beam Directed Energy Deposition Additive Manufacturing of Pure Molybdenum

Advanced Engineering Materials, EarlyView.
Identified through the use of statistical design of experiments and metallographic investigation, this study exposes the stochastic origins of intergranular cracks in blown powder laser beam directed energy deposition additive manufacturing of pure molybdenum. It further demonstrates a successful crack mitigation approach with direct correlation to the

Some Properties of Positive Solutions for Nonlinear Systems Involving Pseudo-Relativistic Operators

Fractal and Fractional
In this paper, we mainly investigate the radial symmetry and monotonicity of positive solutions for a nonlinear system involving pseudo-relativistic operators and fractional derivatives of order (0,1).

Positive radial solutions of n-dimensional elliptic systems with indefinite weight functions and n parameters

Advances in Difference Equations, 2019
Under simple conditions on f and a, we show the existence of positive radial solutions for the n-dimensional elliptic differential system {Δu(x)+Λa(|x|)f(u(x))=0,R10,x∈Rn,n≥2 $\mathbf{x}=(x_{1},x_{2},\ldots ,x_{n})^{T}, \mathbf{u}(\mathbf {x})=(u _{1 ...
