Modeling of Joints in Crash Simulation
For the efficient assembly of components and complete structures many different joining techniques are available. Joints have to ensure that the assembly will fulfill crashworthiness, durability and other requirements. Therefore the best joining technique has to be selected for each application. Modern lightweight design often uses a material mix. Using different materials, like various steel grades, lightweight alloys, plastics or composites for applications for which the individual material is best suited allows for weight savings. The efficient and reliable joining of different materials is even more challenging. Failure of joints can be a reason for collapse of vehicle structures during crash testing. Therefore failure of joints must be precisely predicted in numerical crash simulation applied in the virtual design process of vehicle development.
Who should attend?
The course addresses engineers working in the field of crash simulation and heads of simulation departments interested in the important topic of modelling of joints including failure.
The objective of this one day course is to give the participants an overview of failure modelling of different joints (punctiform, linear, planar joints) for crash simulation and also of the characterization tests and methods that are necessary for calibrating the model parameters. Also recommendation for validation tests and simulations of calibrated joint models are given. Examples of typical and used models are shown in all common crash codes.
