The influence of anisotropy of gallium oxide crystal properties on the magnitude and distribution of shear stresses in slip systems is investigated. An algorithm of calculating shear stresses for crystals of monoclinic syngony is presented. Equivalent slip systems are found. A comparison of shear thermoelastic stresses distributions in various slip systems for thin gallium oxide ribbons grown from a melt by the Stepanov method (EFG) is carried out. A correlation between shear stresses calculated in the ribbon with orientation [010] (210) and the experimental data at the dislocation structure is found. Keywords: monoclinic syngony, transition matrix, equivalent systems.
