A new method for identification of texture in agricultural machinery with interpolation of biaxial anisotropy of elastic modulus of thin-plate polycrystalline elements has been developed. The dependence of shear modulus and modulus of longitudinal elasticity as a function of an angular distribution of Poisson’s ratio, achieved by the method of ulrasonic critical-angle refractometry (UCR), has been derived.

Key words : anisotropy of elastic modulus, thin-plate polycrystalline elements, ulrasonic critical-angle refractometry, ultrasonic non-destructive testing
