WebApr 13, 2024 · Abstract. In the current development of flexible multibody dynamics, the efficient and accurate consideration of distributed and nonlinear forces is an active area of research. Examples are, forces due to body-body contact or due to elastohydrodynamics (EHD). This leads to many additional modes for representing the local deformations in the … 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.
