Mechanical performance analysis of functionally graded triply periodic minimal surfaces

AIP Advances
To address the issue of a single gradient direction in the gradient design of triply periodic minimal surfaces, two functional gradient schemes, trapezoidal and W-shaped, were proposed based on the stress distribution range of the uniform thickness ...

Field Report from Collaborative Research Center 1625: Heterogeneous Research Data Management Using Ontology Representations

Advanced Engineering Materials, EarlyView.
A unified research data management framework for heterogeneous materials data is presented. The system integrates multimodal datasets using ontologies and knowledge graphs, enabling interoperability and FAIR (findable, accessible, interoperable, reusable) data principles. By linking data across scales and workflows, it supports reproducible, Artifitial

Karl Popper and the Mechanisms of Hydrogen Embrittlement

Advanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Experimental investigation of Triply Periodic Minimal Surfaces for high-temperature solar receivers

Case Studies in Thermal Engineering
This study experimentally investigates Triply Periodic Minimal Surfaces (TPMS) as structured porous media for concentrated solar power systems. Two mock-up planar solar receivers with different TPMS lattices, Diamond and SplitP, were fabricated using ...

Computation of Implicit Representation of Volumetric Shells with Predefined Thickness

Algorithms, 2021
We propose and validate a method to find an implicit representation of a surface placed at a distance h from another implicit surface. With two such surfaces on either side of the original surface, a volumetric shell of predefined thickness can be ...

Density-functional theory and triply-periodic minimal surfaces

Physical Review Materials
Several authors have suggested that the surfaces of vanishing potential generated by the electrostatic fields from a periodic distribution of point charges resemble triply-periodic minimal surfaces (TPMS) whose symmetry corresponds to the positions of the point charges.

Modular Critical Element Recycling Platform Using a Nanoporous Additively Manufactured Gyroid

Advanced Engineering Materials, EarlyView.
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

Ontology‐Aligned Structuring and Reuse of Multimodal Materials Data and Workflows Toward Automatic Reproduction

Advanced Engineering Materials, EarlyView.
Reproduction of stacking fault energy calculations from literature with a semi‐automated large language model‐assisted extraction procedure: extraction of simulation protocol, atomistic structures, computational parameters, and reported results, ontology alignment, knowledge graph construction and, finally, recomputation forvalidation.

Optimization of graded porous acoustic absorbers based on triply periodic minimal surfaces

Materials & Design
The acoustic absorption of a porous structure within a specific frequency range can be tuned by varying its porosity along its thickness. In this work, triply periodic minimal surfaces (TPMS) are employed to generate graded porous structures, where the ...
