AbstractThis paper investigates the impact effects of the ribbed sheet with three V-grooves by the nonlinear dynamic FEM. The numerical models considered the nonlinear constitutive equation with strain rate effect, large deformation theory, and self-contact control. The full histories of deformation in simple model, complete model and adaptive model are simulated successfully. With the different groove depths of 3, 4, 7, 10, 12 and 15 mm, different mesh types, and boundary conditions, the correspondent results of simulations are assessed. Detail discussions of the absorbed energy and buckling resistance of the different ribbed sheets on varying boundary conditions are presented. Furthermore, the various mesh types are examined in the simulations. And, the results of simulations are compared with the previous experimental works; the impact load of the suggested numerical model is in good agreement with the experiment. The main benefit of the proposed models will save the tremendous costs in the die designing and specimen producing while on the experimental works. The applied techniques of the numerical models are helpful for the design of ribbed sheets and correspondent impact analysis. © 2009 Elsevier Ltd. All rights reserved.
