In the present work, was carried out an analysis of the behavior of a vehicle body with different characteristics and in different impact conditions. In addition, the factors contributing to traffic accidents were examined and the parameters of a crash test took also into account. In this parametric analysis the condition is studied dynamically and the solution follows the explicit method and shows non-linearity due to the large deformations, the non-linear behavior of the materials and the sudden contact. Finally, the simulation of the collision and the macroscopic approximation of the structure’s behavior were conducted using the Finite Element Method (FEM). This study aims to monitor the deformations, stresses, strain and the produced energy proportional to the element discretization, the speed, the construction material, the structure thickness and the impact angle. Additionally, results are limited in time as all tests last 23 ms for computational reasons. The ultimate goal is the designation of a safer construction according to the evaluation of various crash conditions. It can be assumed that the speed reduction and the carbon fiber as a construction material contributes significantly to improved results in all tests. In addition, the proper discretization size provides a more accurate computational and virtual representation. Generally, non catastrophic crash tests commit economically to the improvement of passive and active vehicle safety.
