内容简介

Young''s modulus is a fundamental mechanical property of a material. This test method is used to determine the dynamic modulus of elasticity of rectangular shapes. Since the test is nondestructive, specimens may be used for other tests as desired. This test method is useful for research and development, engineering application and design, manufacturing process control, and for developing purchasing specifications. The fundamental assumption inherent in this test method is that a Poisson''s ratio of 1/6 is typical for heterogeneous refractory materials. The actual Poisson''s ratio may differ. 1.1 This test method covers a procedure for measuring the resonance frequency in the flexural (transverse) mode of vibration of rectangular refractory brick or rectangularly shaped monoliths at room temperature. Young''s modulus is calculated from the resonance frequency of the shape, its mass (weight) and dimensions. 1.2 Units8212;The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.2.1 Although the Hertz (Hz) is an SI unit, it is derived from seconds which is also an inch-pound unit.1.3 This standard does not purport to address all of the safety concerns, if any,associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
