Numerical and theoretical studies about in-plane impact properties of Semi-Reentrant structures

The in-plane impact and crushing properties have been studied for the Semi Reentrant structure (SRS) by using numerical simulations and theoretical studies. Different deformation modes during impact process could be observed under the various impact velocities, and there were three and two deformation modes in x1 and x2 directions, respectively, no matter for single or double sidewall conditions. The influence of arm length l and cell wall...
