用肘

Contacts under Partial Slip,esultant tangential force is transmitted from one body to another. Secondly, there must be some degree of relative tangential displacement between the contacting surfaces so that slip takes place during cyclic variation of the applied load. In Chapter 2, two types of contact were analysed:

Introduction,brittle fracture. It is relatively easy to design against yield; this simply requires the determination of a composite stress parameter from the individual stress components, and this parameter is maintained below the value of the yield stress at all points. Design against brittle fracture is more d

Basic Contact Mechanics,. 2.1. In cases such as this it is really quite impossible to consider modelling the contact by anything other than a numerical method, and the technique chosen will in many cases be the finite element method. It must be remembered when doing such modelling that care needs to be exercised: not only

Advanced Contact Mechanics,st reading and studied after crack analysis techniques have been mastered. Three specific topics are covered, viz. the influence of elastic material mismatch, contacts subjected to torsion, and the presence of layers in the contacting bodies, including the influence of finite thickness. All of these

The Analysis of Cracks,er which cracks do not arise, or at any rate do not grow. Traditional approaches to the quantification of fatigue have relied on the assumption that the nominal stress in the absence of the crack is sufficient to determine its behaviour. The classical experiments of Wöhler were designed to measure t

Fretting Fatigue Tests,s for determining the state of stress, strain and displacement, but do not, in themselves, permit production of initiation or crack propagation criteria, without extensive experimental data. The object of fretting fatigue tests must be to permit monitoring of fretting fatigue crack propagation and,

Analysis of crack propagation,of the early stages of fatigue itself. It is into this second category that . fatigue falls. The fretting process must first initiate an embryo crack and then propagate it in order to produce a failure. The life of a component suffering fretting fatigue may therefore be conveniently divided into ini
