Tube Expansion by Single Point Incremental Forming: An Experimental and Numerical Investigation

Metals, 2021
In this paper, we revisit the formability of tube expansion by single point incremental forming to account for the material strain hardening and the non-proportional loading paths that were not taken into consideration in a previously published ...

From Top to Bottom: Manufacturing Process‐Context Aware Resolution of Energy Device Electrodes Through a 3D Diffusion Generative Model

Advanced Energy Materials, EarlyView.
The application of a generative diffusion model, enhanced with a training data augmentation pipeline retaining the manufacturing process context of electrode microstructures, leads to improved fidelity of the through‐plane tortuosity factor in the AI generated samples.

Cusps and Triaxiality

The Astrophysical Journal, 1997
Statler (1987) demonstrated that self-consistent triaxial models with the perfect density law could be constructed for virtually any choice of axis ratios. His experiments are repeated here using triaxial mass models based on Jaffe's density law, which has a central density that diverges as 1/r^2, similar to what is observed in low-luminosity ...

An Automated Triaxial Testing System Using a Simple Triaxial Cell for Soils

Soils and Foundations, 1989
A triaxial testing system developed for testing soils under automatically controlled stress paths and strain paths is described. This system consists of a micro-computer and a pneumatic pressurizing system, together with a mechanically simple system consisting of an ordinary axial displacement-controlled loading frame and an ordinary triaxial cell ...

A Two‐Stage Characterization Pipeline and Open‐Source Framework for Reproducible Tactile Sensing

Advanced Intelligent Systems, EarlyView.
The same soft tactile sensor returns different numbers when embodied in different robots. This is an Embodiment Gap that no shared framework currently captures transparently. A two‐stage characterization pipeline, paired with a FAIR open‐source digital datasheet, decouples intrinsic sensor behavior from embodiment effects and condenses cross‐laboratory
