本文是将边圆角引入弹性平板冲头解的新方法的第二部分。基于第一篇文章中提出的用四分之三平面作为圆边有限冲头问题的渐近线的概念，我们现在将观测点移到接触的最边缘，并引入局部接触牵引力的渐近线，以便在分析中考虑剪切，以解决部分滑移问题。利用边缘渐近线得到滑移区的大小以及法向和切向接触牵引力分布，其中接触的圆边可以合理地近似为半平面。
This paper is the second part of a new approach to introduce edge rounding into elastic flat punch solutions. Building on the concept developed in the first paper of using a three-quarter plane as an asymptote to the finite punch with rounded edge problem, we now move the observation point to the very edge of the contact and introduce asymptotes for the local contact tractions so that shear may be included in the analysis to solve the partial slip problem. The edge asymptotes are used to obtain the slip zone size and the normal and tangential contact traction distribution, where the rounded edge in contact can be reasonably approximated by a half-plane.
