我们开发了一种方法,部分滑动接触问题的解决方案遭受复杂的加载周期,一般情况下,正常的负载,剪切力,并可能,差分体积张力都是时间的函数,使用边缘渐近线的方法。滑动区的大小和局部剪切牵引力的分布被揭示为时间的函数。结果然后重新加工的渐近形式,使他们不铰链的固有对称性和反对称条件的接触整体,并具有普遍适用性。局部解的乘数(广义应力强度因子)也适合作为实验室试验量化微动疲劳的一种手段,并将其用于完全不同的原型问题。
We develop a method for the solution of partial slip contact problems suffering complex loading cycles where, generally, the normal load, shear force and, potentially, differential bulk tensions are all functions of time, using an edge-asymptote approach. The size of the slip zone and local shear traction distribution are revealed as functions of time. The results are then re-worked in asymptotic form, so that they do not hinge on inherent symmetry and anti-symmetry conditions for the contact overall, and are of general applicability. The multipliers on the local solutions (generalised stress intensity factors) are also appropriate as a means of taking laboratory tests quantifying fretting fatigue and employing them to wholly different prototypical problems.
