abstract

Many researchers have studied computer-aided simulations of elastic bodies undergoing large deflections and large deformations. But there have been few attempts to validate the numerical formulations used in these studies. The main aim of this paper is to validate the absolute nodal coordinate formulation (ANCF) by comparing the results to experimental measurements on beams. Physical experiments with a highspeed camera were carried out to capture the large displacement of the beam and to verify the results of computer simulations. To consider the damping forces, Rayleigh’s damping and quadratic damping are employed and compared to the experimental results. Numerical results obtained from computer simulations were compared with the results from the physical experiments according to the 1st mode and the 2nd mode of the beam, respectively.
