Location & approach

By car

From highway “A1”

At intersection “Dortmund/Unna” change to highway “A44” in the direction of Dortmund, which becomes the B1. Take the exit “Dortmund-Dorstfeld”, in the direction of “Universität”. Turn right onto “Planetenfeldstraße”, after 850 meters turn left onto “Otto-Hahn-Straße”. After 1 km turn right onto “Marie-Curie-Allee”, after 550 meters keep slightly right to stay on “Baroper Straße”.

From highway “A45”

Take the exit “Dortmund-Eichlinghofen”, in the direction of “Universität”. Turn right onto “Stockumer Straße”, after 800 meters turn left onto “Baroper Straße”.

Please use parking lot entrances 40 or 41 for access to the “Maschinenbau III” building or entrance 42 for access to the Experimental Hall.

By bus and train

Arrival with DB to Dortmund or Bochum central station.
From Dortmund central station take the interurban train line S1 in the direction of Düsseldorf and get off at the stop “Dortmund Universität S”.
From Bochum central station with the interurban train line S1 in the direction of Dortmund and get off at the stop “Dortmund Universität S”
From the interurban stop “Dortmund Universität S”, take the elevated railway (“H-Bahn” stop “Universität S”) to the stop “Campus Süd”.

By plane

From Dortmund Airport

Take a cab to the TU Dortmund University, South Campus (“Campus Süd”) or take the AirportExpress in 20 min. to Dortmund central station. From there take the interurban train line S1 line in the direction of Düsseldorf to the stop “Dortmund Universität S” and from there the elevated railway (“H-Bahn”) to “Campus Süd”.

From Düsseldorf Airport

Take the interurban train line S1 in the direction of Dortmund and get off at the stop “Dortmund Universität S”. From here, take the elevated railway (“H-Bahn”) in the direction of “Campus Süd”.

Plan of site & interactive map

Passive Granular Medium-Based Tube Press Hardening

a) Process schematic, b) Required corner forming pressure, c) Cross section of a formed part

Funding	German Research Foundation (DFG)
Project	427196185
Contact	Siddharth Upadhya M. Sc.

Owing to their high temperature resistance and pressure withstanding capability, granular materials such as zirconia or quartz allow the process combination of hydroforming and press hardening. The active version of the process combination was already successfully implemented and investigated. Due to the non-hydrostatic distribution of pressure inside the medium, the length of the formable part is highly limited.

To overcome this drawback, the passive process variant was developed and is currently investigated. Unlike in the active process variant, the form giving tools apply the required forming pressure and the granular medium has a passive supporting function and prevents the buckling of the tube walls. The required internal pressures are less than 15 % of that required in the active process and as an additional benefit the thickness of the part is homogenous throughout the part, thus aiding in lightweight design. In the next steps, a tool prototype will be developed and further investigations on the process and product properties will be conducted.
