“…Thereby, the strain reached in tensile or compressive deformation of materials is limited and does not match real forming or cutting process, where plastic strains larger than = 2 or 3 can be observed (e.g. [3], [4]). Especially the stress softening behavior due to recrystallization processes during deformation cannot be measured by compression or tensile tests.…”

This paper gives an overview of different testing facilities and the mechanical material behavior including monoaxial and multi axial testing under high rate loading . Special emphasis is laid on difficult loading conditions and loading states such high temperature and high strain loading ( >1200°C, >1) and multiaxial impact tests. The impact behavior of selected materials is shown and compared under different loading conditions. Furthermore, a distinction is made between virgin and manufactured material behavior (e.g. welding) or predamaged materials. Specifically, if the influence of the manufacturing history is investigated, under certain loading states the impact material properties show a dramatic difference compared to the virgin state of the material. Some examples of different material behavior under the conditions previously described are given.
