High speed forming
The strain rate dependence of plastic yield and failure properties displayed by most metals affects energies, forces and forming limits involved in high speed forming processes. At DyMaLab, the influence of the strain rate on the forming properties of several sheet metals isstudied. An approach was developed to predict dynamic forming limit diagrams (FLDs) based […]

Dynamic high pressure torsion
At DyMaLab, a novel dynamic high pressure torsion (SPD-HPT) facility is available. This unique experimental setup imposes a torsional deformation to a sample subjected to a high hydrostatic pressure. The extremely high power transfer to the material (i.e. 105 up to 109 times higher than conventional severe plastic deformation processes) aims at obtaining out-of-equilibrium processing […]
Dynamic bulge testing
In order to characterise dynamic forming properties of sheet metals, at DyMaLab a setup is developed that imposes controllable and adjustable deformation paths to metal sheet samples. The setup combines basic features of split Hopkinson compression bar setups and static bulge tests. The facility not only allows to determine dynamic forming limits of metals, however, […]
