Advanced technical ceramics - Mechanical properties of monolithic ceramics at room temperature - Part 2: Determination of Young's modulus, shear modulus and Poisson's ratio
Abstract
This document specifies test methods for determining the elastic moduli, specifically Young's modulus, shear modulus and Poisson's ratio, of advanced monolithic technical ceramics at room temperature. This document specifies four alternative methods for determining some or all of these three parameters: a) Method A - the determination of Young's modulus by static flexure of a thin beam in three- or four-point flexure; b) Method B - 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; c) Method C - the determination of Young's modulus, shear modulus and Poisson's ratio from the time-of-flight of an ultrasonic pulse; d) Method D - the determination of Young's modulus from the fundamental natural frequency of a struck thin beam (impulse excitation method). All the test methods assume the use of homogeneous test pieces of linear elastic materials. With the exception of Method C, the test methods assume that the test piece has isotropic elastic properties. Method C can be used to determine the degree of anisotropy by testing in different orientations.
