In-plane crushing behaviors of the RHC and the 1 + 1 RHC3.1. Finite element models. In this section, the length of inclined cell wall l 1 is 2.7 mm, the length of the horizontal cell wall l 2 is 2.7 mm, and the angle θ is 60° for RHC, 1 + 1RHC and HC. Additionally, the RHC and the 1 + 1RHC have 16 cells in y direction and 15 in x direction.
