When selecting a suitable protective material, it is first necessary to ensure that the characteristics of the homogeneous materials have been tested and assessed in accordance with their intended use. Here, factors such as strength and deformability under impact-like loading rates play an important role, permitting a basic assessment of the potential protective materials.

Toughness is also a crucial factor when selecting the materials that will be used for protective purposes. For this reason, we collaborated with partners we developed a tester that can be used to quickly assess toughness. This test is a modified drop-weight tear test.

As vehicle protection also makes use of material composites or joints (e.g., welded and bonded joints), these must also be tested and assessed regarding their suitability as protective materials. Extensive tests have been conducted on welded steel joints, for example. The issue here is to be able to provide stronger and tougher welded joints in response to increasing threats. These welded joints can be characterized in terms of impact dynamics by means of various testing methods. In addition, by determining the local material behavior, it becomes possible to provide important characteristic data for the representation of the weld seam in FE simulation.
