On Navier-Stokes equations arising from the rotation of an obstacle in a fluid
Tahar Zamène Boulmezaoud, Nabil Kerdid, Amel Kourta
We consider the modified Navier-Stokes equations in R3 describing the motion of a fluid in the presence of a rotating rigid body. Weighted Sobolev spaces are used to describe the b…

Unification of the mathematical model of elastic perfectly plastic solids: a convex analysis approach
Tahar Z Boulmezaoud, Boualem Khouider
A new mathematical formulation for the constitutive laws governing elastic perfectly plastic materials is proposed here. In particular, it is shown that the elastic strain rate and…
