[en] Thermodynamics of the Bi₂Te₃ monocrystals deflections is studied. The sample reinforcement with thin steel rods, positiond perpendicularly to the cleavage plane, was used for changing the cleavage form. It is found that reinforcement increases the samples strength limits for bending δ more than by two times. It is shown that transition from one type of bending to another leads to essential change of the energy dissipation spectra in the sample by deformation. Certain aspects of practical application of the observed effects are considered
