Abstract

A multibody dynamics formulation based on a nonlinear finite element method is presented particularly targeting beams connected with hinges. A nonlinear kinematics called direct strain measure is employed to extract strains of beams subjected to large displacements included finite rotations. Hinges are mathematically expressed in terms of the relations between connecting nodes rather than Langrange multipliers. The resultant dynamic equation is a differential equation of minimum set of degree of freedom. The sparsity of mass and stiffness matrices are preserved. Computational examples prove the validity of the proposed method.
