A study on plastic strain accumulation caused by traveling of temperature distribution synchronizing with temperature rise

Mechanical Engineering Journal, 2016
The prevention of excessive deformation by thermal ratcheting is important in the design of high-temperature components of fast breeder reactors (FBR). This includes evaluation methods for a new type of thermal ratcheting caused by an axial traveling of ...

Self‐Expanding Cardiovascular Stents: Potentials and Challenges of Shape Memory Biomaterials

Journal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 114, Issue 6, June 2026.
ABSTRACT Cardiovascular diseases affect a large portion of the global population and remain leading causes of morbidity and mortality. Endovascular stenting, a minimally invasive procedure, enables the insertion and deployment of stents to restore arterial patency without open surgery.

On the ratchet analysis of a cracked welded pipe [PDF]

, 2011
This paper presents the ratchet limit analysis of a pipe with a symmetric crack in a mismatched weld by using the extended Linear Matching Method (LMM). Two loading conditions are considered: i) a cyclic temperature load and a constant internal pressure;

Shakedown analysis of red mudstone fill material with different water contents

Journal of Rock Mechanics and Geotechnical Engineering
Understanding the shakedown behavior of fill material is paramount to estimate the deformation stability of railway subgrade. Especially for red mudstone fill material (RMF), the noticeable overestimation of bearing capacity would be encountered if the ...

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 ...
