Hilber-hughes-taylor method
Webusually solved with Newton-Raphson methods. For some typical implicit methods, such as the Newmark-β methods [4] and the Hilber-Hughes-Taylor-α method [5], the stability is guaranteed only for linear problems. However, for nonlinear problems, the stability is doubtful and often depends on the specific problem and the step size adopted in the ... WebHilber, Hughes, and Taylor (1978) present cogent arguments for the use of Equation 2.4.1–2–Equation 2.4.1–4 for 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.
