Popis:	A study is made of the conditions of second harmonics generation by an elastic wave in crystals of tetragonal (TI), cubic and hexagonal systems. The full system of equations is given which make it possible to determine the third order elastic constants and their combinations by measuring the second harmonic amplitude. The dependence of the derivatives of the second harmonic amplitude with respect to the stress tensor on the fourth order elastic constants is found for an arbitrarily deformed crystal.
