摘要

一组新的滑线场，以及相应的计算程序，为高法向压力和地下变形下的凹凸不平提供了解析解。这种新的解决方案整合了现有的在高压下的光滑场和与压痕相关的滑动场，并提供了在平面应变条件下向均匀地下变形的静态允许过渡。计算过程有效地管理了从一个滑线场到另一个滑线场的过渡，考虑了实际接触面积比和与地下变形相关的纵向应变的增量。通过数值模拟验证了新解的有效性。

Slipline solution to asperity deformation under combined high normal pressure and subsurface deformation

A new set of slipline fields, along with a corresponding calculation procedure, offers an analytical solution to the flattening of asperities under high normal pressure and subsurface deformation. This new solution integrates existing slipline fields for asperity flattening at high normal pressures with those related to indentation and provides a statically admissible transition to uniform subsurface deformation under plane strain conditions. The calculation procedure effectively manages the transition from one slipline field to another, accounting for increments in both the real contact area ratio and the longitudinal strain associated with subsurface deformation. The new solution is validated against numerical simulations.
