BRUSH BERYLLIUM QMV MATERIAL: DYNAMIC. MODULUS OF ELASTICITY AND RUPTURE MODULUS AT ROOM TEMPERATURE
The methods and results of an investigation to determine the dynamic modulus of elasticity, Young's modulus of elasticity, and the rupture modulus of Brush beryllium QMV block material at room temperature are presented. The dynamic modulus of elasticity was obtained by both a beam vibration and a wave propagation method. A beam deflection method was used to substantiate that the test material does not have a significant proportional limit and consequently has no Young's modulus. Bending of a simply supported beam was used to determine the rupture modulus. The general results obtained were in close agreement with anticipated properties based on earlier tensile and compressive tests. (auth)
