Simulation of fatigue behaviour in fusion welded 2024-T351 [PDF]

, 2004
A model has been developed to predict short crack fatigue life in the fusion zone of Metal Inert Gas (MIG) welded 2024-T351, based on the observed propensity for complex, multiple cracking processes in this region.

Multimodal Perception and Machine Learning‐Empowered Human Machine Interfaces With Double‐Network Hydrogel Fibers

Advanced Functional Materials, EarlyView.
This work develops polyacrylamide‐alginate (PAM‐Alg) double‐network hydrogel fibers for multimodal perception and intelligent human‐machine interfaces. The covalent‐ionic network provides high strength, toughness, and stable conductivity. Easily woven into wearables and integrated with soft robots, the fibers enable object and temperature recognitions ...

Multi-timescale analysis of fatigue crack growth on interfaces via cohesive-zone models [PDF]

, 2014
The paper describes a new non-linear finite-element formulation to analyse fatigue debonding or delamination, along predefined interfaces, which is multi-scale in time. At the small timescale level, cyclic loading and the related oscillating response are
