The 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.

The dynamic elastic modulus of alloys near stoichiometric CuZn, FeCo and Fe3Al were measured using transverse vibration of unrestrained cylindrical specimens. Test frequencies were in the range 700 to 3000 c. Internal friction measurements were made concomitantly using both the free-decay and half-width methods. Measurements on CuZn were in vacuo using a novel radiation heating furnace. Experiments on FeCo and Fe3Al were in air with an applied magnetic field of 1500 oersteds to eliminate magnetic damping phenomena. Creep studies on CuZn were conducted in compression and on FeCo in torsion. (Author).

The effect of temperature on Young's modulus of elasticity was determined for 2024-T3 and 7075-T6 aluminum alloys, AZ31A-0 magnesium alloy, RS-120 titanium alloy, and type 303 stainless steel by flexural vibration test of beam specimens at temperatures from room temperature to 900 degrees F. The test frequencies were varied from 40 to 550 cycles per second. The results are compared with values of moduli obtained from conventional stress-strain tests. The data show that the dynamic modulus decreases with temperature but does not decrease as rapidly as the static modulus. It is shown that the difference between the static modulus and dynamic modulus is due to internal friction and cannot be attributed to creep.

A symposium on Aerothermoelasticity was held to present the latest significant developments in each scientific area and engineering area that comprise the component parts of this technology. New and significant contributions were presented in four technical areas consisting of dynamic aerothermoelasticity (flutter), stability and control, thermodynamics and aerodynamics (or aerothermodynamics), and structures including material and construction concepts. Categories important and significant to each technical area are discussed state-of-the-art wise. In addition, 26 separate papers are given on items of special importance.
