In this study, first energy absorption of axial and bending loading is considered. Next, thin walled structures under oblique loading are investigated using ABAQUS computer simulation, where 180 different cases are simulated. Simulation results of the thin walled structures under oblique loading were compared with the experimental results of Nagel, and good agreement was perceived. Simulation results revealed that, the amount of energy absorption for thin walled structures is reducing with collision angle. Moreover, the energy absorption performance of thin walled structures can be controlled by geometric parameters; in particular, thickness as one of the most effective parameters in controlling the amount of energy absorption must be considered.
