2.1 Definitions

Crimping poses a number of problems commonly observed on crimped steel or aluminum alloy sheets.

  • Although not detrimental to the aesthetics of the vehicle, winding is a geometrical problem, as it modifies the final dimensions of the crimped part, making them imprecise. It is therefore essential to have a reliable numerical simulation to predict this value and control the clearance between a door and its cabin side. As shown in figure 8 , this is more precisely a material shrinkage occurring during the process. It can be deduced from direct measurement of the dimensions of specimens L t ...
