Adhesive joints of the car body have to conserve their integrity under crash loading and thus allow the whole structure to consume a large amount of dissipation energy. To meet the respective requirements the glue must exhibit high ...

In general the body-in-white (BIW) consists of thin walled structures joined with adhesives, spot welds, laser welds etc. Due to the efficiency and reliability of laser welding, it is increasingly applied in automotive applications to ...

Im vorliegenden Beitrag wir ein materialkonsistentes mathematisches Modell für isotrope, plastisch kompressible Klebschichten mit Berücksichtigung des Dehnrateneinflusses und der Entfestigung vorgestellt. Das Modell wurde aus einer ...

Structural adhesives have been introduced to increase the stiffness and crashworthiness, as well as to improve corrosion protection and sealing of the body-in-white in upper class car models and are now entering the segment of compact ...

The phenomenological description for the mechanical behaviour of ductile, toughened polymers is currently an active field of research in interfacial mechanics, since the recently developed crashmodified adhesives are well suited to ...

This paper investigates the possibilities of emulating car to car crashes with small lateral offsets by means of a simpler single vehicle crash test. By analyzing existing accident databases for accidents with small lateral offsets, a ...

This presentation gives an introduction and motivation into the topic of Crash Barrier Models for LS-DYNA. It includes modelling methods, the current progress of barrier model creation, correlation to test as well as the release ...

Edge fracture prediction using CAE Kimihito Koyanagi, Kazuyoshi Motomura Toyota Auto Body Co., Ltd. (Kariya, Aichi, Japan) Kenichi Watanabe, Mie Tachibana Kobe steel, Ltd. (Kakogawa, Hyogo, Japan) Summary: In the vehicle collisions, ...

At vehicle collisions, fractures occur from the edge of steel sheet. Existence of any fracture has an influence on the accuracy of vehicle crash simulations. In order to obtain a simple evaluation index of the fracture limit, fracture ...
