Unsteady-state flows of media that possess a complex of rheological properties such as elasticity, viscosity and plasticity are studied. The fluid is assumed to exhibit elastic properties at stresses below the fluidity limit. A Trikomi-type boundary-value problem for describing the unsteady-state forced flows in these media is formulated. A difference scheme for the unobstructed calculation is constructed, and the conditions of its efficiency are investigated. The numerical results obtained illustrate the essential effect of elastic properties in the region where the stress is below the fluidity limit; in particular, those cases are studied wherein the period of the elastic shear wave is commensurable with the characteristic hydrodynamic time of the process.
