Does Long‐Term Lower Extremity Strength Training in Adults With Knee Osteoarthritis and Varus Alignment Reduce Knee Joint Loading During Gait?

Arthritis Care &Research, EarlyView.
Objective We examined whether 18 months of strength training in individuals with knee varus alignment and medial tibiofemoral osteoarthritis (OA) reduced knee joint loads during walking compared to an attention control group. Methods This study was a secondary analysis of a randomized clinical trial that compared the effects of strength training to a ...

EBSD characterization of martensitic transformation and texture evolution in lean duplex stainless steel under uniaxial loading

Journal of Materials Research and Technology
In this work, EBSD technique was applied to investigate the martensitic transformation characteristics and texture evolution laws in a lean duplex stainless steel (present LDX) along several uniaxial loading paths (i.e., tension, compression, cyclic ...

Experimental Evaluation of 100Cr6 Steel Microindented Surfaces Under Lubricated Nonconformal Point Contacts

Advanced Engineering Materials, EarlyView.
The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

Dynamic Compression Properties and Deterioration of Red-Sandstone Subject to Cyclic Wet-Dry Treatment

Advances in Civil Engineering, 2019
Rock engineering is usually associated with impact loads induced by blasting, drilling, vibration, or earthquake. In the engineering fields of tunnelling, slopes, dams, and mining, rocks are always subjected to cyclic wet-dry caused by periodical ...

Ratcheting behavior of PTFE under cyclic compression

Polymer Testing, 2005
Abstract In this paper, loading rate dependence of stress–strain response and ratcheting behavior under compression for PTFE were studied. The effects of loading rate, mean stress and stress amplitude on the ratcheting behavior of PTFE are discussed.

Electrochemical Evaluation of Compressed Selective Laser Melted AlSi7Mg and AlSi10Mg Alloys in Chloride Environment

Advanced Engineering Materials, EarlyView.
The corrosion performance of AlSi7Mg and AlSi10Mg alloys produced through selective laser melting (SLM) was examined under compressive stress in a chloride environment. Electrochemical analyses, including open‐circuit potential (OCP), potentiodynamic polarization (CPP), and electrochemical impedance spectroscopy (EIS), were complemented by scanning ...

Strength degradation of sandstone and granodiorite under uniaxial cyclic loading

Journal of Rock Mechanics and Geotechnical Engineering, 2018
Change in mechanical properties of rocks under static loading has been widely studied and documented. However, the response of rocks to cyclic loads is still a much-debated topic.
