[en] An investigation is made of the effects of tidal distortion on the stability of stars in binary systms against the development of turbulence and convection. Attention is limited to systems in which the stellar spin axis is perpendicular to the plane of the binary orbit. A short-wavelength linear stability analysis of an incompressible stellar model with laminar flow and tidally induced shear uncovers no instabilities. The analytic results of that analysis are supplemented by various heuristic considerations and used to argue in favor of the following statements: (ii) Tidal effects should not interfere with convection or turbulence which would be present in the absence of tidal distortion. (iii) It is not currently possible to decide whether or not tidally induced shear can cause turbulence through nonlinear instabilities
