Keywords: dissipative Rayleigh–Taylor instability, biological materials, instability increment, bipolar electric welding


The dissipative Rayleigh–Taylor instability, which can arise at the interface between biomaterials under the action of high-frequency currents, has been considered. A mechanism describing the formation of a corrugated boundary of the mesomorphic phase is proposed. The corrugation period and depth are evaluated.
