Study of Viscoplastic Flows Governed by the Norton-Hoff Operator

الملخص EN

We deal with viscoplastic flows.

The fluid motion is governed by the nonlinear incompressible Norton-Hoff operator with homogeneous boundary conditions.

We provide the well-posedness of the model in the static case.

The idea is based on the crucial properties of the so-called compliance functional coupled with the min-max theory relayed to a variational analysis of the associated Lagrangian.
