WebHilber, Hughes, and Taylor (1978)present cogent arguments for the use of Equation 2.4.1–2–Equation 2.4.1–4for integrating structural dynamics problems. The main appeal of the operator is its controllable numerical damping and the form this damping takes, slowly growing at low frequencies, with more rapid growth in damping at high frequencies.
