Computer-aided analysis and design of the shape rolling process for producing turbine engine airfoils [PDF]

open access: yes
Mild steel (AISI 1018) was selected as model cold rolling material and Ti-6A1-4V and Inconel 718 were selected as typical hot rolling and cold rolling alloys, respectively.

Testing the assumption of linear dependence between the rolling friction torque and normal force

open access: yesMATEC Web of Conferences, 2017
Rolling friction is present in all nonconforming bodies in contact. A permanent topic is the characterization of the moment of rolling friction. A number of authors accept the hypothesis of linear dependency between the rolling torque and the normal ...

Advances in Safe, Flexible, and Stretchable Batteries for Wearable Applications

open access: yesAdvanced Materials Technologies, EarlyView.
Unlike previous reviews centered on component‐based deformability, this work highlights safety‐driven design strategies for flexible and stretchable batteries. By integrating material‐level engineering, geometry‐controlled structures, biocompatibility, and self‐protection mechanisms, it establishes a unified framework that connects mechanical ...

On line estimation of rolling resistance for intelligent tires [PDF]

open access: yes, 2016
The analysis of a rolling tire is a complex problem of nonlinear elasticity. Although in the technical literature some tire models have been presented, the phenomena involved in the tire rolling are far to be completely understood.

Rack-and-pinion effects in molecular rolling friction

open access: yes, 2008
Rolling lubrication with spherical molecules working as 'nanobearings' has failed experimentally so far, without a full understanding of the physics involved and of the reasons why.

Multiobjective Codesign Optimization of a Planar Pneumatic Artificial Muscle‐Based Snake‐Like Robot for Enhanced Agility and Energy Efficiency

open access: yesAdvanced Robotics Research, EarlyView.
A codesign multiobjective optimization framework was developed to enhance the morphology and controller of a snake‐like robot driven by artificial muscles. It improved planar locomotion, agility, and power efficiency. The approach optimized link geometry and controller gains, revealing that shorter muscles near joints and longer linkages maximize ...
