Mass stiffness damping
WebIf an undamped structure is allowed to vibrate freely, the magnitude of the oscillation is constant. In reality, however, energy is dissipated by the structure's motion, and the … Web•Rayleigh damping is convenient mathematically as it is still linear and proportional to the mass and the stiffness as we will see with just two terms. •Let’s again recall the general matrix form of the equation of motion; •We can then express the damping matrix to be linearly proportional to the Mass and Stiffness matrices.
