Reducing the downtime of hydraulic systems of the machine park that is accompanied by economical loss can be achieved by maintenance, service and protection of these systems. For the purpose of protection bursting disks are used.

Bursting disks are predetermined breaking points of the hydraulic system, to drain the fluid or gas controlled off. These bursting disks are conventionally formed quasi static and without the help of numerical simulations.

This research joint venture aims to produce the bursting disks by electromagnetic high velocity impact forming. A numerical simulation to describe this process is established.

The focus is on how the two different forming processes are influencing the bursting behavior. Key parameters are the elevated strain rates and the usage of a variety of different forming elements to control the bursting behavior.
