DOWNLOAD EBOOKThe dynamic elastic moduli of 40 metals and ALLOYS OF ENGINEERING INTEREST HAVE BEEN DETERMINED AT ROOM AND ELEVATED TEMPERATURES. Modulus determinations were based upon a relation between the speed of sound in a material and its elastic modulus. A specimen of the material was excited electrostatically and its resonant frequency determined. Knowing the geometry of the specimen, the dynamic elastic modulus was calculated. Room temperature comparisons of dynamic with static moduli were made in most instances using material from the same bar. The results of dynamic elastic modulus determinations are graphically presented.

DOWNLOAD EBOOKThe results of a round-robin testing study are presented for measurements of dynamic Young's modulus in two nickel-based alloys. The Interlaboratory Testing Program involved six types of apparatus, six different organizations, and specimens from a well-documented source. All the techniques yielded values of dynamic Young's modulus that agreed within 1.6% of each other. For Inconel alloy 600 the dynamic modulus was 213.5 GPa with a standard deviation of 3.6 GPa; for Incoloy alloy 907 the corresponding values were 158.6 and 2.2 GPa, respectively. No significant effect of frequency over the range 780 Hz to 15 MHz was found.

DOWNLOAD EBOOKDynamic modulus measurements are of interest in materials research not only as a source of data on elastic behavior, but also for the insight they provide into structure-property relationships in general. A description is given of a vibrating-reed apparatus which has proved highly adaptable for studies of the elastic and damping behavior of thin-film and other thin-layer electronic materials. Results are reported for amorphous and crystalline ferromagnetic materials, for the high-Tc superconducting oxide Y1Ba2Cu3O7-x, and for thin films of aluminum and silicon monoxide, to illustrate the important role which the dynamic modulus can play as a tool in materials research.

DOWNLOAD EBOOKA round-robin study usually attempts to have several laboratories measure identical materials by the methods used in each laboratory. Similarly, the methods usually are expected to produce comparable absolute errors if used properly. Round-robins then have the facility to detect gross errors in one operation vis-à-vis the mean and standard deviation of the remainder of the set.

DOWNLOAD EBOOKThe impulse excitation technique is a dynamic method of measurement based on the analysis of a transient vibration of the test object resulting from a mechanical impact. The result is a precise indication of the fundamental natural frequency of this vibration. This information may be used as the basis for calculating the elastic moduli of the material under test. The natural frequency reading by itself may be used as a relative measure for the purpose of comparative evaluation. The technique is characterised by the speed and ease of the measurements as well as by the wide range of its application. Because of this, the method is not confined to the laboratory environment but opens new perspectives in industrial quality control and performance improvement.
