Explicit cylindrical maps for general tubular shapes
Computer-Aided Design, 2017 A solid cylindrical parameterization is a volumetric map between a tubular shape and a right cylinder embedded in the polar coordinate reference system. This paper introduces a novel approach to derive smooth (i.e., harmonic) cylindrical parameterizations for solids with arbitrary topology.

Ear height control by die radius shape in cylindrical deep drawing [PDF]
MATEC Web of ConferencesThis study presents the relationship between die radius shape and anisotropy that suppresses ear height in cylindrical deep drawing. In deep drawing, the cup is formed with irregularities on the edge, called “earing”, due to the anisotropy of sheet ...

Advanced Engineering Materials, EarlyView.The corrosion performance of AlSi7Mg and AlSi10Mg alloys produced through selective laser melting (SLM) was examined under compressive stress in a chloride environment. Electrochemical analyses, including open‐circuit potential (OCP), potentiodynamic polarization (CPP), and electrochemical impedance spectroscopy (EIS), were complemented by scanning ...

Effect of the shape of the cuff on blood pressure measurement in people with large arms
Blood Pressure, 2020 Purpose: Previous data suggest that tronco-conical cuffs should be used for accurate blood pressure (BP) measurement in the obese. However, not only arm size but also its shape may affect the accuracy of BP measurement when a cylindrical cuff is used ...

Advanced Engineering Materials, EarlyView.Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

Advanced Engineering Materials, EarlyView.Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Advanced Engineering Materials, EarlyView.This article presents the design, modeling, and characterization of air‐pressure–actuated programmable vibroacoustic metamaterials (PVAMM). The study focuses on leveraging air pressure to dynamically tune resonance frequencies for effective noise attenuation.
