The weak solvability of an inhomogeneous dynamic problem
for a viscoelastic continuum with memory
V. G. Zvyagin, V. P. Orlov Voronezh State University
Abstract:
The existence of a weak solution to the initial boundary value problem for the
equations of motion of a viscoelastic fluid with memory along the trajectories of a nonsmooth velocity
field with inhomogeneous boundary condition is proved. The analysis involves Galerkin-type approximations
of the original problem followed by the passage to the limit based on a priori estimates.
To study the behavior of
trajectories of a nonsmooth velocity field, the theory of regular Lagrangian flows is used.
Keywords:
viscoelastic continuum, a priori estimate, weak
solution, regular Lagrangian flow, trajectory.
