    "abstract": "A model for harmonic oscillator damping due to the internal friction of\nsolids has been developed, based on considerations of a long period pendulum.\nThe assumption of a complex elastic modulus to describe stress-strain\nhysteresis in the support structure of the pendulum yields an expression for\nthe figure of merit Q that agrees with many experiments involving material\ndamping. As such, the approximations of this linear model stand in contrast\nwith common theory.",
