Advanced technical ceramics - Mechanical properties of monolithic ceramics at room temperature - Part 2: Determination of Young's modulus, shear modulus and Poisson's ratio; German version EN 843-2:2006
This standard specifies methods for determining the elastic moduli, specifically Young's modulus, shear modulus and Poisson's ratio, of advanced monolithic technical ceramics at room temperature, namely the following four alternative methods for determining some or all of these three parameters: Method A: determination of Young's modulus by static flexure of a thin beam in three- or four-point flexure; Method B: determination of Young's modulus by forced longitudinal resonance, or Young's modulus, shear modulus and Poisson's ratio by forced flexural and torsional resonance, of a thin beam; Method C: determination of Young's modulus, shear modulus and Poisson's ratio from the time-of-flight of an ultrasonic pulse; Method D: determination of Young's modulus from the fundamental natural frequency of a struck bar (impulse excitation method).
