“…LSDYNA explicit FE code has been used for FE models development, solution, and postprocessing. Using the model development procedure described by Fotopoulos et al, 35 a mesh convergence study has been conducted, resulting to the conclusion that a basic element size of 5 mm for the developed FE models leads to sufficiently accurate results. Panels have been modelled using 4 sublaminates, ie, 4 shell elements though-the-thickness, as shown in Figure 7B, meaning that one sublaminate per 12 layers of composite material has been used.…”

“…Panels have been modelled using 4 sublaminates, ie, 4 shell elements though-the-thickness, as shown in Figure 7B, meaning that one sublaminate per 12 layers of composite material has been used. Using the model development procedure described by Fotopoulos et al, 35 a mesh convergence study has been conducted, resulting to the conclusion that a basic element size of 5 mm for the developed FE models leads to sufficiently accurate results. According to the stacked shell approach, proper contact conditions have been defined between each pair of sublaminates using the *CONTACT_AUTOMATIC_ SURFACE_TO_ SURFACE_TIEBREAK keyword of LS-DYNA code.…”
