Advanced Engineering Materials, EarlyView.A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

Generalized quadratic Gauss sums and their 2mth power mean
Open MathematicsThe main purpose of this article is to study the problem of calculating the 2mth power mean of the generalized quadratic Gauss sums, and using the analytic method and an interesting combinatorial identity to give a sharp asymptotic formula for the 2mth ...

Advanced Engineering Materials, EarlyView.This study examines how helicoidal architectures with different porosities respond to bending. Adjusting layer angle and spacing in 3D‐printed polymers reveals clear tradeoffs between stiffness, strength, and energy absorption. Experiments and simulations highlight designs that distribute stress effectively, offering pathways for optimizing lightweight

Sharp bounds for Sándor-Yang means in terms of quadratic mean [PDF]
Journal of Mathematical Inequalities, 2018 Summary: In the article, we find the best possible parameters \(\alpha,\beta,\lambda,\mu\in(1 /2,1)\) such that the double inequalities \[ Q[\alpha a+(1-\alpha) b,\alpha b+ (1-\alpha)a] < R_{QA}(a,b)< Q[\beta a+ (1-\beta)b,\beta b+ (1-\beta)a], \] \[ Q[\lambda a+ (1-\lambda) b,\lambda b+(1-\lambda)a] < R_{AQ}(a,b)< Q[\mu a+ (1-\mu)b,\mu b+(1-\mu)a ...

Advanced Engineering Materials, EarlyView.Postbuild annealing systematically modifies the phase fractions and morphology of EB‐PBF processed Mo–9Si–8B. Quantitative microstructure–property correlations reveal how controlled phase evolution enhances high‐temperature compressive strength and creep resistance.

Abstract and Applied Analysis, 2012 We present the best possible lower and upper bounds for the Neuman-Sándor mean in terms of the convex combinations of either the harmonic and quadratic means or the geometric and quadratic means or the harmonic and contraharmonic means.

Advanced Engineering Materials, EarlyView.Sustainability assessment requires methodologies that appropriately distinguish between additive and non‐additive material properties. A toxicity‐weighted scoring system is developed and applied that accounts for the disproportionate influence of highly toxic constituents through nonlinear weighting functions, providing more realistic estimates than ...
