“…Notice that Eq. (7) is consistent with the results of experimental studies [17,21,22,40,[48][49][50] and molecular dynamics simulations [29][30][31]37], On the other hand, it is easy to understand that the maximum ridge length is always less than or equal to the folded ball diameter. Furthermore, it is a straightforward matter to deduce that in the limit of p -» 1 the width of all ridges is equal to Wmin = ji h and so /max -> /m in -Consequently, in this limit, the total number of ridges is expected to be equal to…”
