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

FATIGUE FAILURE OF NICKEL-TITANIUM INSTRUMENTS IN ENDODONTICS AND ITS INFLUENCING FACTORS
Česká Stomatologie a Praktické Zubní Lékařství, 2022 Introduction and aim: The fracture of Ni-Ti instruments is a complication that most dentists will sooner or later encounter in the dental office. There are mainly two basic mechanisms behind it and these are exceeding the cyclic fatigue limit, exceeding ...

Mechanisms of femoral fracture [PDF]
Journal 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.

The 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 ...
