摘要

．在本文中，我们回顾了一些经典的和最近的工作，模拟滑动接触与磨损，并提出他们的推广。也就是说，我们通过加入一些非局部时间依赖性来升级压力与磨损率之间的关系。为了达到这个效果，我们结合了分数微积分和松弛效应。此外，我们还考虑了载荷在时间上不恒定的可能性。对所提出的模型进行了分析和求解。对结果进行了数值说明，并与同类模型进行了比较。

A generalised time-evolution model for contact problems with wear and its analysis

. In this paper, we revisit some classical and recent works on modelling sliding contact with wear and propose their generalisation. Namely, we upgrade the relation between the pressure and the wear rate by incorpo- rating some non-local time-dependence. To this eﬀect, we use a combination of fractional calculus and relaxation eﬀects. Moreover, we consider a possibility when the load is not constant in time. The proposed model is analysed and solved. The results are illustrated numerically and comparison with similar models is discussed.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
