Similarity methods for analysing indentation contact problems—Advantages and disadvantages Review Article

In this review article similarity methods for analysing indentation contact problems are explored and related advantages and disadvantages discussed in some detail. In particular, combined elastic and plastic effects, together with, and also taken separately from, the influence from large deformations, are discussed in the context of a self-similarity analysis. The main conclusion of the present investigation is that a self-similarity approach to indentation problems is of significant advantage at many circumstances while, however, limitations of such methods have to be carefully accounted for at application.
