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 ...

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 ...

Chinese Journal of Mechanical Engineering, 2022 In aerospace engineering, design and optimization of mechanical structures are usually performed with respect to elastic limit. Besides causing insufficient use of the material, such design concept fails to meet the ever growing needs of the light weight
