渐近解的接触压力和剪切力的边缘附近的不完全接触的推导，并为每个尺寸的比例因子（类似于广义应力强度因子），定义。因此，这两个量可以用来定义完整的局部应力状态，为此目的，导出了Muskhelishvili势。这种技术的应用比较赫兹-Cattaneo接触，平坦和圆形的接触和平铺冲头的描述，并发现的渐近线的有效性域的程度。
Asymptotic solutions for the contact pressure and shearing tractions present adjacent to the edge of an incomplete contact are derived, and for each a dimensional scaling factor (akin to a generalised stress intensity factor), is defined. These two quantities may therefore be used to define the complete local stress state, for which purpose the Muskhelishvili potentials are derived. The application of this technique to a comparison of the Hertz–Cattaneo contact, the flat and rounded contact and the tiled punch is described, and the extent of the domain of validity of the asymptote found.
