Impact of Surface Roughness on the Yield Drop of Hot‐Rolled AZX311 Mg Alloy
Advanced Engineering Materials, EarlyView.Rough‐surfaced AZX311 Mg alloy samples have significantly lower yield strength than polished ones due to stress concentrators forming at V‐notch irregularities. Surface profilometry confirms higher Ra values for rough samples. Highest hardness values were observed near scratched surfaces, indicating strain localization effects near the rough surface ...

Thurston's bending measure conjecture for once punctured torus groups [PDF]
arXiv, 2004 We prove Thurston's bending measure conjecture for quasifuchsian once punctured torus groups. The conjecture states that the bending measures of the two components of the convex hull boundary uniquely determine the group.

Bioinspired Design of Isotropic Lattices with Tunable and Controllable Anisotropy
Advanced Engineering Materials, EarlyView.This study introduces nested isotropic lattices, integrating architectural elements like nesting orders and orientations inspired by bioarchitectures. The design enables tunable anisotropy across nine mono‐nest and twenty multi‐nest lattices with 252 parametric variations, demonstrating transitions from shear‐ to tensile‐compression‐dominant behaviors ...

Three dimensional graph drawing with fixed vertices and one bend per edge [PDF]
arXiv, 2016 We prove that for every graph $G$, given fixed locations for the vertices of $G$ in $\mathbb{Z}^3$, there is a three-dimensional grid-drawing of $G$ with one bend per edge. The best previous bound was three bends per edge.

Arquivo Brasileiro de Medicina Veterinária e ZootecniaRESUMO Fraturas ósseas podem ser corrigidas com a utilização de fixadores esqueléticos externos (FEE), método de estabilização bastante comum. Para tanto, têm-se utilizado barras conectoras de polimetilmetacrilato (PMMA) sem critério de diâmetro, as ...

Advanced Engineering Materials, EarlyView.Mechanical metamaterials capable of compressive stiffness tunability, shape morphing, and post‐fabrication modularity. Herein, the 3D unit cell design is based on an assembly of bistable von Mises trusses that exhibit a switch in compressive stiffness and resting height from one stable state to the other.

Effect of spring-back in v-tool bending of high-strength steel sheet metal plates
Metalurgija, 2013 This paper deals with the effects of technological parameters used in the V-die bending process, on the obtained product properties and dimensions. By variation of the tool geometry, several cases of steel sheet bending process are observed through the ...

Advanced Engineering Materials, EarlyView.This perspective article explores an innovative powder metallurgical approach to producing high‐nitrogen steels by utilizing a mixture of stainless steel and Si3N4. This mixture undergoes hot isostatic pressing followed by direct quenching. The article also examines adapting this method to laser powder bed fusion (PBF‐LB/M) to overcome nitrogen ...
