Inverse Identification of Energy‐Dependent Laser Absorptivity in NiTi Laser Powder‐Bed Fusion via Calibrated Melt Pool Simulation

open access: yesAdvanced Engineering Materials, EarlyView.
A combined experimental–computational framework identifies energy‐dependent laser absorptivity for NiTi in laser powder‐bed fusion, applicable to conduction and transition modes. Single‐track experiments and thermofluid smoothed particle hydrodynamics simulations are coupled through inverse analysis of melt pool geometry.

Comparison of Triply Periodic Minimal Surface Energy Absorbers Under Uniaxial Compressive Loading

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates LCD 3D printed Triply Periodic Minimal Surface (TPMS) structures as mechanical energy absorbers. By comparing various base designs and layered combinations under uniaxial compression, it identifies that a Diamond‐Gyroid sandwich structure offers superior performance.

Preparation and characterisation of inks for let printing onto textile materials [PDF]

open access: yes, 2004
The feasibility of using thermal drop-on-demand ink jet printing to print pigmented ink systems onto textile materials was investigated. Preliminary studies showed that a novel binder system, Synthappret BAP (traditionally used as a shrink resist ...

Elucidating spatial heterogeneities in 3D printed thermoplastic elastomers using micro-beam small-angle x-ray scattering [PDF]

open access: yesStructural Dynamics
3D printing is uniquely capable of producing architectures with hierarchically ordered structure from the nano-scale through the macro-scale (cm). One primary approach by which 3D printing can tune nano- and meso-scale material anisotropy is through the ...

Architecture‐Driven Sensor Stability in Weft‐Knitted Engineering Textiles

open access: yesAdvanced Engineering Materials, EarlyView.
Textile‐integrated sensor architectures are systematically compared to evaluate their electromechanical behavior under combined mechanical and environmental loading. Pocket‐based integration exhibits stable and reproducible signals, whereas tunnel‐based routing shows higher sensitivity accompanied by increased variability.

Investigation of novel 3D-printing methods for freeform construction

open access: yes, 2021
3D Concrete Printing (3DCP) is a technique of sequentially layering of cementitious material to create a three-dimensional structure. Recently, it has gained much attention for its advantages, such as customized production, waste reduction, and increased

The evolution in perception of journalism history in the works of English and American researchers

open access: yesУченые записки Казанского университета: Серия Гуманитарные науки, 2017
The aim of this paper is to trace the development of journalism history as an independent subfield in English and American historiography beginning with its spring from the sphere of book printing. Comparing the pioneering works of Anglo-American authors

An Explicit Constitutive Reconstruction Framework for Mechanical Characterization of Miniaturized 3D‐Printed Specimens

open access: yesAdvanced Engineering Materials, EarlyView.
An explicit constitutive reconstruction framework enables accurate tensile characterization of miniaturized additively manufactured specimens using only the grip‐to‐grip displacement measurements. Progressive validation through self‐consistency, analytical comparison, and inverse finite element method (iFEM) benchmarking demonstrates constitutive ...
