Influence of Timing of Postoperative Weight-Bearing on Implant Failure Rate Among Older Patients With Intertrochanteric Hip Fractures: A Propensity Score Matching Cohort Study

open access: yesFrontiers in Medicine, 2021
Introduction: The purpose of this study was to determine whether immediate weight-bearing as tolerated increased the risk of implant failure and decreased functional outcomes compared with restricted weight-bearing.Methods: From January 2010 to December ...

Experiment and Numerical Study of Wear in Cross Roller Thrust Bearings

open access: yesLubricants, 2015
Bearings are essential parts used in machine tools where high precision is required. It is important to understand bearing failure in order to replace a bearing before it affects the quality of precision.

Experimental Study on Characteristics of Pile-Soil Interaction in Screw Piles

open access: yesBuildings, 2022
A screw pile is a special-shaped pile with several advantages, including good bearing capacity, economy, and rapid construction. The calculation of the screw piles’ ultimate bearing capacity in the individual bearing failure state remains controversial ...

Failure Analysis of a Cylindrical Roller Bearing Caused by Excessive Tightening Axial Force

open access: yesMachines, 2022
The premature failure of a cylindrical roller bearing took place during service, with a total operation time of 100 h. The failure cause was analyzed by macroscopic and microscopic observation, metallographic analysis, hardness testing, tightening axial ...

Rolling Bearing Fault Diagnosis Based on the Coherent Demodulation Model

open access: yesIEEE Access, 2020
The rolling bearing is an important part of rotary machineries and the health state monitoring is currently a hot research topic. There are four typical failure modes of a rolling bearing: the inner race failure, the outer race failure, the rolling ...

Experimental study on reinforcement effects of bonded steel plates of highway tunnels under different damage degrees

open access: yesYantu gongcheng xuebao, 2023
The cracking damage of linings is a common damage form of tunnels, which directly affects the bearing capacity of the structure. The reinforcement of bonded steel plates is widely used as the structural reinforcement, but there are few researches on the ...
