Compression and outflow of an asymptotically thin perfectly rigid-plastic spherical layer
Д. В. Георгиевский · Moscow University Mechanics Bulletin · 2011
The axisymmetric meridional flow of an incompressible perfectly rigid-plastic medium between two concentric rough spheres is studied in the case of a sink. The outer sphere is fixed, whereas the surface of the inner sphere is uniformly expanded. An asymptotic integration of a boundary value problem with a natural small geometric parameter is performed.
