Crushing analysis and crashworthiness optimization design of .
· An automatic singlesurface contact algorithm is defined to account for the contact of the column itself during deformation, while an automatic nodetosurface contact is used between HSP and rigid wall. For both static and dynamic friction, the friction coefficient of is adopted for all contact conditions. Figure 1:
