Investigations of internal friction and constants of elasticity of solids by the acoustic resonance method
Abstract
Results of measurements of the internal friction, Poisson's constant and Young's modulus for various metals: copper, aluminium, copper without oxygen, brass, aluminium and silicon bronzes, in different states of deformation and heat treatment, were presented. Discovery of the formerly unknown anomaly of internal friction in a plastically deformed silicon bronze BK31, occurring in the temperature range 400-500K, was discussed. A number of effects that accompany this phenomenon were described, together with attempts of explanation of its physical mechanism.References
