Testing steel plates with high explosives (IMAGE) Norwegian University of Science and Technology Caption In recent decades, new threats have emerged, and the need to protect civil buildings and structures in urban areas has increased. Therefore, other types of materials must be tested and researched. How do thin steel sheets behave when subjected to extreme stress loads? Here, PhD candidate Benjamin Stavnar Elveli (right) and supervisor Vegard Aune, both from the Norwegian University of Science and Technology, prepare a test rig for detonating high explosives in confined spaces. The tests are carried out at the Norwegian Defence Estates Agency’s test facility, in collaboration with researcher Ole Vestrum (back).
