Abstract

In order to reduce the computation time and increase the convergence rate of absolute nodal coordinate formulation (ANCF), this paper gives a new local mesh refine method that can densify the mesh locally according to the degree of stress concentration. The mesh is divided into two kinds after comparing the maximum of the stress at each nodes with the average stress of the total fine mesh. The density of the new mesh is decided by the degree of stress concentration. The example that a rectangle plate fixed at four corner nodes with concentrate force applied at the center of the plate is simulated by fully parameterized ANCF plate element is given to verify our method.
