Rayleigh Damping
Rayleigh Damping : A form of damping used in the matrix analysis of structures in which the damping matrix is a constant times the mass matrix plus another constant times the stiffness matrix. Rayleigh damping produces viscous damping factors in the modes that are dependent on the natural frequencies of the modes. The constants are chosen to produce desired damping factors over the important modes of response. See: Jennings (2003), and the biography of Lord Rayleigh in Howell (2003)
