%X Assuming the smallness of the internal friction which depends only on the amplitude of shear strain, based on analytical mechanics, we developed a calculation method to obtain non-linear material parameters of internal fiction and shear modulus from the sampled data of tor-sional displacements of the free-decay oscillation for the torsional pendulum.
