Abstract

In multibody system dynamics, the absolute nodal coordinate formulation (ANCF) uses power functions as interpolating polynomials to describe displacement field. It can get accurate results for flexible bodies that undergo large-deformation and large-rotation. In this paper, an eight-node ANCF solid element has been provided and achieved. The continuity equations have been used to maintain the consistency for multiple elements, and the viscosity model has been proposed for the large deformations. The constraint equations and motion equations are developed based on the continuum mechanics theory for the solid element. Numerical results are presented to validate the feasibility of proposed element. It is shown that the proposed element can lead to a better convergence in comparison with the conventional finite elements in the dynamic analysis.
