The project has developed spotweld failure models capable of industry application for a range of steel grades to support development of automotive products, and their compliance to international crash safety requirements. An important ...

Presently, there are various cohesive zone models implemented in LS-DYNA. The simplest one consists of a bi-linear traction separation-law in both modes I and II. Further models allow more complicated shapes of the traction-separation ...

This report is an initial investigation in to the effect of pre-stress of bolts during impact. The conclusions are not definitive but do indicate that for large strain analysis the effect of pre-stress in bolts is minimal. The effects ...

Over the last years, total vehicle weights have risen significantly. With their direct influence on the power demand of vehicles, the reduction of weight is one among other measures in order to decrease the fuel consumption and ...

For the customer, passive safety is one of the driving reasons for the decision when buying a new car. To ensure high safety standards, passive safety is demonstrated in vehicle crash tests. Instead of vehicle to vehicle crash tests, ...

Cellbond and ARUP have launched their advanced crash barrier models in 2006 and since the time a continuous study has been carried out to distinguish costumer requirements and review feedbacks. Existing barrier models are constructed ...

The standards which fixes guidelines for the execution of crash tests to assess the effectiveness of safety barriers in USA and Europe, define an experiment with a low weight passenger car. Such an investigation’s aim is to evaluate ...

As one of the important issues in correlation of crash analysis, we know that the press-forming effect has large influence for the result of the analysis. Some tries and studies were carried out to assume the forming result to the ...

Road safety barriers in Europe have to fulfil the European standard EN 1317, which defines a set of crash tests for each safety barriers containment levels. Full scale tests of vehicle collision against road safety barriers have a ...

One major component of fuel cell vehicles is the hydrogen storage system. A promising and nowadays mostly used approach is to store hydrogen in wet wound carbon fiber reinforced plastic (CFRP) vessels manufactured by filament winding ...
