What is BS EN 843-2 – Young’s modulus of monolithic ceramics about?
BS EN 843 is a European standard series that discusses advanced technical ceramics. BS EN 843-2 is the second part of the series that specifies Young’s modulus, shear modulus and Poisson’s ratio, of advanced monolithic technical ceramics at room temperature. BS EN 843-2 provides four alternative methods for determining some or all of these three parameters:
The determination of Young’s modulus by static flexure of a thin beam in three- or four-point flexure The 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 The determination of Young’s modulus, shear modulus and Poisson’s ratio from the time-of-flight of an ultrasonic pulse The determination of Young’s modulus from the fundamental natural frequency of a struck bar (impulse excitation method)
