The horizontal plane, the plane vertical and perpendicular displacement to the plane, respectively , and , to be verified by the Fig. 6 of the last step. The maximum value obtained in the perpendicular direction is about 95.5 which occurs precisely in the central zone of the panel where the buckling tends to happen. The results obtained via DIC will be later used in another paper, where a more exhaustive comparison will be made with the results obtained numerically. 4. Conclusions A pseudo-dynamic (PSD) test is an experimental practice with the advantage of providing accurate and reliable results. The dynamic model associated to the structure can be approached as a single degree of freedom (SDOF) model. The deformation evolution with time (virtual time) can usefully inform about the structure behaviour due to its modes of damage propagation. This techinique allows the user the access of a couple results providing the dynamic behavior of a structure. A PSD test is frequently used since it is a cheaper solution compared with a dynamic setup. The experimental test was successful, the high precision in the positioning of the door, and its fixation to the test bench platform were key factors. With this test, it is possible to verify in real time the propagation of damage of the door what would happen during a frontal impact of the bus. The final deformation of the door highlights the possibility of opening it in an emergency case to rescue the occupants. The structure that is analyzed here, is considered as a slender structure, this means the possibility of occurring buckling is high, which could cause unexpected behavior and could lead to serious risks. Thus, it is extremely important to ensure that the positioning of the door is accurate, as well as the alignment of the load cell during the test. The last point that should be discussed is the the digital image correlation processing provided full-field data for displacement and strain values, showing how every region of the door behaved during the PSD test. These results as those obtained by the PSD test algorithm will allow future analysis with numerical results.
