Improving the cycle fatigue life of spring steel by a novel thermal cycling process

open access: yesMaterials Research Express, 2021
A novel thermal cycling process was applied on the 65Mn spring to improve the cycle fatigue life. Results demonstrate that the cycle fatigue life after the thermal cycling process was improved from 3 times to 14 times, with an improvement of 470%.

Design of fixed blast valve for gas extraction grouting sealing device

open access: yesMeikuang Anquan, 2021
Taking practice of gas extraction and sealing hole grouting in coal mine as background, a new type of blast valve was developed in view of the current situation that the existing blast valves can not meet the requirements of new grouting sealing device.

FRACTURE MECHANICS [PDF]

open access: yesThe Journal of Bone and Joint Surgery. British volume, 1961
1. Linear fractures of the shaft of the long bones are divided into four basic types: 1) transverse; 2) oblique transverse; 3) spiral; and 4) oblique. 2. The mode of production of these fractures is deduced on the grounds of simple mechanical theory: 1) transverse fractures are a result of angulation; 2) oblique transyerse are the result of ...

Mechanisms of femoral fracture [PDF]

open access: yesJournal of Biomechanics, 1980
Abstract Mechanisms of femoral fracture of the condyles and shaft were experimentally investigated through controlled knee impact of denuded femurs in six human cadavers. High-speed movies recorded knee joint compression, femoral displacements and deformation, and fracture initiation.
