Nonadiabatic Study of Dynamic Electronic Effects during Brittle Fracture of Silicon [PDF]

, 2012
It has long been observed that brittle fracture of materials can lead to emission of high energy electrons and UV photons, but an atomistic description of the origin of such processes has lacked.

A fabrication history based strain-fatigue model for prediction of crack initiation in a radial loading wheel [PDF]

, 2017
A strain-based fatigue model concerning fabrication history is applied to predict the fatigue life of a commercial car wheel under radial loads. As the prior conditions, the strain fatigue testing is performed on standard specimen of DP590 and FB540 ...

Associations of Sleep and Shift Work with Osteoarthritis Risk

Arthritis Care &Research, Accepted Article.
Objective Daily rhythms may be critical for maintaining homeostasis of joint tissues. We aimed to investigate the relationships between circadian clock disruption, sleep, and osteoarthritis (OA) risk in humans. Methods In the UK Biobank, a prospective 500,000‐person cohort, we evaluated associations between sleep duration, sleeplessness/insomnia, and ...

Evaluation of fracture strain of aluminium film by multilayer bulge method

Nihon Kikai Gakkai ronbunshu
As semiconductors become more capacitive and sophisticated, 3D packaging technology is gaining increased attention. Since multiple chips are stacked in such configurations, the wiring structure becomes more complex, leading to stress concentration.

Bistable Mechanisms 3D Printing for Mechanically Programmable Vibration Control

Advanced Engineering Materials, EarlyView.
This work introduces a 3D‐printed bistable mechanism integrated into tuned mass dampers (TMDs) for mechanically adaptive passive vibration suppression. Through optimized geometry, the bistable design provides adaptable vibration reduction across a broad range of scenarios, achieving effective vibration mitigation without complex controls or external ...
