Abstract

CEN ENV 843-2 contains four methods for measurements of elastic moduli of advanced technical ceramics at room temperature: quasi-static flexure (SF, three or four-point bending), beam resonance (R), beam impact excitation (IE), and ultrasonic pulse (UP). To provide information on equivalence of results, repeatability, reproducibility and potential for testing at elevated temperature, an evaluation has been conducted within an EC sponsored project.
