Flows of a Bingham-Il'yushin viscoplastic medium in a symmetric channel / L. V. Muravleva. // Vestnik Moskovskogo Universiteta. Seriya 1. Matematika. Mekhanika. 2012. № 3. P. 65-67 [Moscow Univ. Math. Bulletin. Vol. 72, N 2, 2017. P. 0].

Numerical simulation of viscoplastic incompressible medium flow in a channel with varying width was held. Influence of yield stress and amplitude perturbation of the uniform channel on distribution of rigid zones was investigated.

Key words: viscoplasticity, Bingham-Ilyushin medium, variational inequalities, rigid zones.
