MECHANICAL BEHAVIOR OF BERYLLIUM WIRE REINFORCED PLASTIC COMPOSITES. PART II. TIME DEPENDENT MECHANICAL PROPERTIES.

Abstract

The dependence of the mechanical behavior of beryllium wire reinforced plastic composites on duration of load (creep and stress-rupture), number of loading cycles (fatigue), and vibrational frequency (dynamic modulus and damping) was investigated. Where possible, this behavior is compared with that of the constituent beryllium wire and other structural materials. The stress at which plastic deformation commences (elastic limit) in beryllium wire was determined. The static mechanical properties of beryllium wire which had been acid etched to achieve a smooth surface were determined and were compared with similar properties of as received beryllium wire.
