Investigating Fracture Behavior of Lattice Structures Using the XFEM and Equivalent Solid Material Model Techniques

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 11, Page 4572-4585, November 2026.
ABSTRACT This study aims to numerically investigate the mode I, II, and III fracture behaviors of additively manufactured degradable, bioplastic polylactic acid (PLA) lattice specimens. Numerical simulations were performed using the eXtended Finite Element Method (XFEM) based on the extracted PLA's mechanical and fracture material properties.

Modular Critical Element Recycling Platform Using a Nanoporous Additively Manufactured Gyroid

Advanced Engineering Materials, Volume 28, Issue 19, 7 October 2026.
A modular recycling platform integrates 3D‐printed nanoporous gyroid structures to enable efficient critical element recovery. This system utilizes a hierarchical architecture, combining macroscopic channels with polymerization‐induced nanoscale porosity. By systematically tuning structural wall thickness and resin formulation, the platform achieves an

Verifying calculated dose to the breast in stereotactic radiotherapy: A practical phantom‐based method

Journal of Applied Clinical Medical Physics, Volume 27, Issue 10, October 2026.
Abstract Background Reference dosimetry for the GammaPod breast radiosurgery device is determined in a polymethyl methacrylate (PMMA) phantom, while the clinical dose calculations assume the patient's breast has the atomic composition of water with a density (∼0.935 g/cm3).

Load Distributing Metamaterials Via Discrete Optimization

Advanced Functional Materials, Volume 36, Issue 82, 12 October 2026.
Mechanical metamaterials are computationally optimized to homogenize transmitted forces by minimizing the spread of reaction forces. The resulting architectures transform localized loading into broader, more uniform force distributions and experimentally demonstrate robust load spreading under quasi‐static and impact loading.

From Fiber Bundles to Architected Membranes: Triply Periodic Minimal Surface Architectures for Biohybrid Artificial Lungs

Advanced Materials, Volume 38, Issue 55, 1 October 2026.
Additively manufactured triply periodic minimal surface (TPMS) membranes offer an architecture‐driven alternative to hollow fiber bundles in artificial lungs. Multiphysics simulations and endothelialized prototypes show that the 3D‐printable membrane architecture improves gas exchange, blood flow distribution, and hemocompatibility, enabling ...

The gyroid is embedded and has constant mean curvature companions

, 1995
The gyroid is a triply periodic minimal surface in the associated family of the Schwarz P- and D-surface. We prove it is embedded and find constant mean curvature companions of the gyroid with small constant mean curvature.

Improving Agar Plate Image Quality Using a Low‐Cost 3D‐Printed Lightbox: A Proof‐of‐Concept Evaluation for Machine Learning–Assisted Analysis

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
A low‐cost, three‐dimensional‐printed lightbox improved smartphone‐based agar plate imaging by reducing artifacts and enhancing feature visibility. Standardized lightbox images also supported more interpretable QuPath–assisted colony analysis, with exploratory semiautomated counts showing close agreement with manual reference counts.
