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 … WebAug 5, 2006 · On an Implementation of the Hilber-Hughes-Taylor Method in the Context of Index 3 Differential-Algebraic Equations of Multibody Dynamics (DETC2005-85096) …
WebWe will consider the Hilber–Hughes–Taylor-α (HHT-α ) method to solve periodic second-order initial value problems arising in, e.g. mechanics. We will consider the analysis of the method when applied to such problems. Second-order convergence is theoretically demonstrated and numerically illustrated. http://qu-zhe.net/Resource/Struct/dynamics.pdf
