Webshells with 5 integration points through-the-thickness. For a shell element with 5 integration points through-the-thickness, fully integrated Hughes-Liu formulation requires 35367 mathematical operations compared to the 725 ones for Belytschko-Lin-Tsay formulation. This choice, despite an increase of simulation time, drastically WebThe shell local axes system in LS- DYNA is based on its node numbering, as defined in the User’s Manual [16]. In the convention used in this study, the local x-axis is defined to be parallel to the shell edge connecting its first two nodes. The z-axis is normal to the element mid-plane and the y-axis is determined by the cross product
