Soft Yet Tough Tanglemers Through Rapid Photopolymerization for DLP 3D Printing

Advanced Materials, EarlyView.
Soft yet tough tanglemers are produced through low‐initiator free radical photopolymerization and translated to DLP 3D printing. Systematic control over light intensity, initiator loading, and crosslink density reveals processing windows that balance printability, elasticity, toughness, and feature fidelity. ABSTRACT Additive manufacturing of compliant

A new implementation of the anisotropic plasticity–ductile damage model coupling Hill yield and GTN failure criteria in Abaqus UMAT: Identification of parameters for AA6022

Applications in Engineering Science
This paper adopts a 2D implementation of an anisotropic plasticity–ductile damage model coupling Hill yield and GTN failure criteria and extends it to a 3D implementation in a user material subroutine (UMAT) of Abaqus software.

Epidemiological Profile of Pediatric Ear Nose Throat Emergencies

Journal of Ankara University Faculty of Medicine, 2019
Objectives:Ear, nose and throat (ENT) diseases are among the most common pathologies in the community, some of which may have high morbidity and mortality if early diagnosis and appropriate treatment approaches are not applied. Pediatric patients form an important part of emergency department admissions.

UCST‐Driven Shape Morphing in Digital Light Processing 4D‐Printed Hydrogels

Advanced Materials Technologies, EarlyView.
A DLP‐printable UCST hydrogel based on poly(acrylic acid‐co‐acrylamide) enables reversible thermally induced expansion and 4D shape morphing. Rational control of composition, porosity, and multimaterial architecture enables predictable 4D shape morphing through differential swelling and localized actuation, opening new opportunities for high‐resolution

3D Printed Photon Shield Assembly for Low‐Noise Visual Stimulation During Two‐Photon Imaging in Mice

Advanced Materials Technologies, EarlyView.
We present the Photon Shield, an open‐hardware system for low‐noise two‐photon calcium imaging during visual stimulation in mice. Combining a 3D‐printed headplate and rail‐mounted shield substantially reduces stray‐light contamination, as quantitatively verified. Functional validation confirms reliable cortical responses. Open design files enable broad

Simulation of earing behaviors in bake hardening steel exhibiting a strong off-γ-fiber component [PDF]

, 2012
Analytical theory and a crystal plasticity finite element method (CPFEM) were used to simulate the earing profiles of drawn cups of bake hardening (BH) steel. The two approaches successfully predicted the earing profiles.
