Abstract
The paper presents the methodology and results of the ultrasound determination of material constants of anisotropic materials belonging to the transversely isotropic system. Ultrasound through-transmission method was used for determining material constants. Based on the measurements of velocities of longitudinal and transverse ultrasounds waves propagation, respectively polarized in required directions all the elastic and the material constant of the test materials were determined. Measurements of all the velocities necessary to determine the elastic constants were performed on a specially prepared individual samples. The tests were carried out on porous polycrystalline anisotropic graphites of anisotropy in Young’s modulus of up to 26% and Al2O3 composites with up to 30% of hBN causing anisotropy of Young’s modulus of up to 50%. It was found that for all tested samples the value of Young’s modules and modules stiffness decreasing with increasing porosity in the graphites and increasing content of hBN in Al2O3. © 2016 Elsevier B.V.
