Introduction Bus overturning is one of its most common and tragic accidents. To increase the safety of passengers, the maximum permissible deformation of the bodywork is therefore prescribed so that even in the event of an accident, there is a so-called survival space in the interior of the vehicle. This fact can also be proven by computer simulation, which requires a good knowledge of the mechanical properties of all materials used, the deformation curve of joints up to the area of plastic deformations.
