Reply to Comment on “Director reorientation in nematic liquid-single-crystal elastomers by external mechanical stress”

In their comment E. M. Terentjev and M. Warner try to argue that the results we obtained in ref.  are physically incorrect. To do this they use estimates of the orders of magnitude, and their scaling with cross-linking density, of a number of elastic coefficients. We point out that their arguments are based on their misunderstanding of several basic concepts. First, they confuse the Landau model to describe phase transitions with a macroscopic description of the nematic phase. Second, they apply the technique of a linear stability analysis above the threshold of the instability, where this type of analysis is incorrect.
