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

Advanced Engineering Materials, EarlyView.This study shows that superalloys used in aircraft engine disks become much more prone to deformation at high temperatures if they have been strained during manufacturing. This effect increases with the level of prior strain but eventually reaches a limit.

Artificially cemented sand under multiaxial loading [PDF]
E3S Web of Conferences, 2019 Distinct improvement techniques can be used when civil engineering structures are to be built on soils that do not present suitable mechanical characteristics. The soil improvement techniques can vary from compaction to chemical and mechanical stabilisation. This work focuses on the specific case of granular soils treated with low amount of cement. The

Advanced Engineering Materials, EarlyView.This work studies the anisotropic behavior of circular notched tensile specimens of Ni‐base superalloy single crystals during high‐temperature tensile creep along [001], [110], and [111]. Correlative scale‐bridging imaging of specimens reveals early rupture along [110] because 1) plastic deformation proceeds faster at notch center; 2) more (brittle ...

A multiaxial fatigue life prediction method using a hybrid GRU-FCNN model optimized by grid search
Results in EngineeringMultiaxial fatigue life prediction is critical for the safety assessment of engineering structures. Conventional models are often tailored to specific materials and loading paths, which limits their accuracy and broad applicability under complex ...

The Failure Behavior of an Epoxy Resin Subject to Multiaxial Loading
Pipelines 2006, 2006 The failure behavior of an epoxy resin (EPON 826) was investigated by a series of tests on thin-walled tubular specimens and the results are presented in this paper. The tests were designed such that a constant octahedral shear strain rate was applied along different loading paths.

Advanced Engineering Materials, EarlyView.Functionally graded metal–ceramic femoral stems are engineered through continuous UMAT‐based stiffness tailoring, eliminating discrete material interfaces while enhancing biomechanical compatibility. Low‐index power‐law gradation optimizes load transfer, reduces stress shielding, and controls implant–bone micromotion, highlighting a materials‐design ...
