GB/T 45598-2025 Fine ceramics—Test method of elastic modulus, shear modulus and Poisson’s ratio for ceramic at high temperature—Impulse excitation of vibration

Scope

This document describes the principles, instrumentation, samples, experimental steps, calculations, and test reports for determining the elastic modulus, shear modulus, and Poisson's ratio of fine ceramics in high-temperature environments using the pulse excitation method.
This document is suitable for determining the elastic modulus, shear modulus, and Poisson's ratio of isotropic, continuous, homogeneous ceramic materials in high-temperature environments. It can also be used as a reference for other isotropic, continuous, homogeneous hard and brittle solid materials such as metals and glass.
