Deformations Car Body Joints Under Operating Conditions 861397

In this paper an analysis of the dynamic behaviour of typical bodywork joints subjected to two typical actual load conditions is presented. This analys is carried out by finite element method and experimental verified by holographic interferometry measureuments.
The obtained results show unequivocally that along the weld spots the plate edges tend to detach one from the other and that under operational conditions the weld spots of a car body work essentially by unbuttoning.
