The Study on 3D Incompatible Element in Flexible Multibody System Dynamics

In this study the performance of three-dimensional tetrahedron elements has been compared with the background of the simulation of Flexible Multibody System (FMBS). The standard linear tetrahedron element has the least number of nodes, however it has the locking problem. The standard quadratic element has shown precise result and robust performance in many applications, but its high nodes also means large computational time. The incompatible elements integrates the excellence of the linear and quadratic elements and its excellent performance in term of accuracy and time efficiency is presented.
