A Newmark-Type Integrator for Flexible Systems Considering Nonsmooth Unilateral Constraints
A Newmark-Type Integrator for Flexible Systems Considering Nonsmooth Unilateral Constraints
Mechanical systems are usually subjected not only to bilateral constraints but also to unilateral constraints. Inspired by the HHT time integration method for smooth flexible multibody dynamics, this paper presents a Newmark-type integrator, denoted by nonsmooth HHT method, to include the nonsmooth property of unilateral constraints. Through numerical examples accounting …
