• 11:00 LASCO Umformtechnik GmbH - Energy Efficiency Re-Engineered11:00 - 11:30Frank Osterloh - Lasco Umformtechnik GmbH
  
  Dramatic price increases for energy sources as well as the volatile procurement market for raw materials and semi-finished products - whether in terms of price development or the supply chain problem - are forcing our companies in the solid forming industry to urgently take the necessary measures to be able to counteract in a targeted manner. Solutions must be found to keep the cost increase in production as low as possible and to make production processes as efficient as possible. Therefore - besides the suppliers of raw materials and energy, also the machine tool manufacturers in particular are obliged to reach this target. LASCO is facing the challenges of the forming industry and offers innovative solutions that significantly improve the competitive situation of our customers - despite the aforementioned major challenges. In this presentation, we therefore focus on the innovative technical features of the LASCO forming machines to save production costs. Based on the example of a fully automatic LASCO aluminium forging line, all system components used will be highlighted.

• 11:30 Graphit Kropfmühl GmbH - Forging Industry in Change11:30 - 12:00Gottfried Lang - Graphit Kropfmühl GmbH
  
  The continuously progressing climate change as well as associated increasingly stringent environmental regulations are presenting the forging industry with forward-looking tasks. Especially new technologies in the automotive sector, such as e-mobility and hydrogen power, necessitate a change in the field of forging. The new raw materials used for these purposes, such as aluminum or titanium alloys, also make an adapted lubricant and release agent indispensable. Graphit Kropfmühl GmbH (GK) as manufacturer of graphite-containing dispersions is a reliable partner during this change and will provide its customers with the most suitable lubricant for their applications. Due to own graphite mines located in Europe, Africa and Asia, GK has almost unlimited access to various raw material specifications, with the right one being selected depending on your requirements. During this development process, GK also attaches great importance to current environmental aspects. With customized products, the necessary change can be successfully implemented and offers opportunities for opening up new areas of applications.

• 12:00 Transvalor - Modeling of Ductile Damage Transition to Fracture12:00 - 12:30Dr. José Alves - TRANSVALOR
  
  Until our most recent release, we offered the possibility of simulating damage-to-fracture by means of the element-deletion (or kill-element) technique. While robust and algorithmically simple, this method has several disadvantages among which the virtual loss of mass and the strong dependency of the crack surface to the mesh size. A completely new framework is introduced in this talk based on two concepts: (a) The Phase-Field approach, where a proxy variable is defined to manage damage as a physical field. It goes from 0 for the intact material to 1 for a fully damaged material. (b) The split-element approach, where the damaged elements are cut instead of deleted. The cutting direction is automatically obtained from the Phase-Field and its gradient which enables predicting the onset and propagation of cracks without ad hoc hypotheses.
