Název v původním jazyce

Towards smart porous piezoelectric materials

Popis výsledku v původním jazyce

We consider porous media constituted by piezoelectric porous skeleton with pores saturated by viscous fluid. Such materials are generated as periodic structures using a representative volume element containing the piezoelectric solid part (the matrix) and the fluid saturated pore (the channels). Both the matrix and the channels form connected subdomains. In this work we consider electrically neutral fluid. The macroscopic model is obtained by the homogenization of the microscopic model which involves the quasi-static equilibrium equation governing the solid piezoelectric skeleton, the Stokes model of the viscous fluid flow in the channels and the coupling interface conditions on the transmission interface. Also conductive fibers can be considered which allow for local controlling of the structures by the electric field.
