... sidered as a good reference because it used real accident damage to compare the numerical results. The result in collision energy from the virtual simulation was later verified with the calculation result of the empirical formula. In the extended study, the collision region and material model are selected as influenced parameters to design collision scenarios. The characteristic of collision energy from these scenarios will be discussed. In the same section, the damage pattern is observed and reviewed to find the relation between several parameters to calculation results. It was shown that the influence of region and location of target points contributed significantly to energy dissipation. In contrast, the key finding in material properties is that when Young's modulus between materials was the same and the difference of yield strength of materials was not significant, then other material properties contributed to the result.
