本文分析了宾汉固体在两旋转平板间的二维流动。在平板表面采用最大摩擦定律。在摩擦表面附近的解决方案的渐近分析。它的结果被用于数值计算过程中，以获得一个精确的近似的解决方案附近的摩擦表面。通过厚度分布的速度，等效应变率，和应力示出。强调解决方案的定性特征。与率无关材料的解决方案的结果进行了比较。
An analysis is conducted of the two-dimensional flow of Bingham solids between two rotating plates. The maximum friction law is adopted at the plate surface. An asymptotic analysis of the solution is performed in the vicinity of the friction surface. Its results are used in a numerical procedure to obtain an accurate approximation of the solution near the friction surface. The through thickness distribution of velocities, the equivalent strain rate, and stresses is illustrated. Qualitative features of the solution are emphasized. The results are compared with the solution for rate-independent materials.
