Abstract. Analytical relations for the strain tensor components caused by acoustic waves with arbitrary wave vector directions in crystals are derived. Our approach involves standard rotation matrices and cross sections of the indicative surfaces of Christoffel tensor, which are made by the planes perpendicular to the wave vectors..

Keywords: acousto-optics, acoustic waves, strain tensor

Анотація. Одержано аналітичні співвідношення для компонент тензора деформацій, спричинених акустичними хвилями з довільними напрямками хвильового вектора в кристалах. Підхід базується на стандартних поворотних матрицях і поперечних перерізах індикативних поверхонь тензора Крістоффеля, зроблених площинами, перпендикулярними до хвильового вектора.
