| heal.abstract | The stiffness matrix of AI2O3/ A1203 composites has been non-destructively evaluated using ultrasonics. The method is based on the propagation velocities of sound waves in the material. These were estimated experimentally using a custom pulser-receiver setup which allows control of the angle of the incident pulse on the sample, while the latter is immersed in a water bath. The recording of die time delay of the longitudinal and transverse wave components as they travel through the composite, allows the determination of their respective propagation velocities within die composite, as a function of die incident angle for a given recording plane. .The derivation of die elastic constants in order to reproduce the stiffness matrix of the composite is an inverse wave propagation problem described by the Christoffel equation. All 9 elastic constants are derived assuming an orthotropic medium. The derived elastic constants are compared to experimental data acquired destructively. | en |
