WebDec 8, 2010 · The relation between the step size selection and the structure stiffness is also discussed. The use of the computer implementation described in this paper is demonstrated by solving very stiff structure problems using the Hilber–Hughes–Taylor (HHT) method, which includes numerical damping. An eigenvalue analysis and Fast Fourier Transform ... 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. games chemnitz

Weband the HHT method of Hilber, Hughes & Taylor (1977). The Newmark method with its commonly used values (γ=2β=0.5) is the most accurate unconditionally stable scheme (Dahlquist, 1963), but results in excessive numerical oscillations.
