EFFICIENT LARGE DEFORMATION SIMULATIONS OF MULTI-FLEXIBLE-BODY SYSTEMS USING ABSOLUTE NODAL COORDINATE BEAM AND PLATE ELEMENTS

摘要

In this paper, we investigate the absolute nodal coordinate finite element (FE) formulations for modeling multi-flexible-body systems in a divide-and-conquer framework. Large elastic deformations in the individual components (beams and plates) are modeled using the absolute nodal coordinate formulation (ANCF). The divide-and-conquer algorithm (DCA) is utilized to model the constraints arising due to kinematic joints between the flexible components. We develop necessary equations of the new algorithm and present numerical examples to test and validate the method.
