Behavior of Thin-Walled Structures under Impact Load Using LS-DYNA Codes

In this study, the energy absorption capacity and crushstrength of cylindrical thin-walled structures areinvestigated using nonlinear Finite Element code LSDYNA.For the thin-walled structure, A6063 aluminum isused and its behavior is modeled using power-law equation.In order to investigate the performance of tubes in a betterway, the simulation was also carried out on structures withother types of cross-sections such as triangle, square,rectangle, and hexagonal. It was seen that the circular crosssectionhas the highest energy absorption capacity and crushstrength while they are the lowest for the triangular crosssection.It is concluded that increasing the number of sidesincreases the energy absorption capacity and the crushstrength.
