Pose‐Independent Soft Haptic Ring for Joint‐Centered Directional Guidance via Multichannel Shape Memory Alloy Actuators

Small Structures, Volume 7, Issue 5, May 2026.
The Pose‐Independent Haptic Ring (PIHR) delivers four‐directional, joint‐referenced haptic cues using a compact multichannel serpentine SMA array embedded in a soft elastomer. By mapping circumferential normal indentation to a metacarpophalangeal (MCP)‐centered spherical coordinate system, the PIHR preserves consistent spatial meaning under arbitrary ...

Simulation‐Based Assessment of Second‐Order Residual Stress Fields on the Fatigue Performance of Silicon‐Strengthened Ferritic Ductile Irons

Advanced Engineering Materials, Volume 28, Issue 6, 18 March 2026.
This work presents a simulation‐based framework based on representative volume elements (RVEs) that explicitly incorporates process‐induced second‐order residual stresses into the fatigue strength assessment of ductile cast iron (DCI). For the first time, this approach enables a direct evaluation of the influence of second‐order residual stress fields ...

Memory of Stress History in Single and Two Surface Plasticity for Granular Soils

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 2, Page 597-612, 10 February 2026.
ABSTRACT Recent studies have identified limitations in Manzari and Dafalias' 1997 and 2004 sand plasticity models, particularly regarding one‐way unloading/reloading and ratcheting loading modes. These models are widely accepted as bounding surface models in the geotechnical engineering community; thus, concerns have arisen about a fundamental lack of ...
